Focus Group Post-Cancellation Billing: The Invoice That Should Not Exist

"I Cancelled. Why Am I Still Being Billed?"

It is one of the most frustrating patterns in the 1-star reviews on uk.trustpilot.com/review/focusgroup.co.uk. A business cancels. They receive written confirmation. Then weeks or months later, an invoice lands. Or a direct debit hits. Or, worse, a debt collection letter.

We are Compare The Networks, an independent, OFCOM-regulated business telecoms comparison service. This article walks through why post-cancellation billing happens, your legal position, and exactly how to respond so that you do not end up paying for a service you already cancelled.

Why Post-Cancellation Invoices Happen

Internal Process Lag

Billing systems and cancellation systems often do not talk to each other. You can cancel on 1 March, get confirmation, and still have a 5 April invoice generated because the billing system ran before the cancellation was reflected.

Disputed Notice Period

Focus Group may interpret your notice date differently from you. If you said "cancel at end of month" on 20 March and they insist your notice period is 30 days, the cancellation takes effect 19 April — three weeks later than you expected.

Additional Services Not Cancelled

If your contract bundles mobile, VoIP and broadband, cancelling the mobile does not automatically cancel the other two. Some reviewers describe partial cancellations being misunderstood as full cancellations.

Handset or Equipment Finance

Device finance balances can continue after service cancellation. Check your contract.

Cessation Charges

On connectivity (fibre, leased lines), there are often Openreach cessation charges when the service is stopped. These can be £100+ and are usually legitimate if they are in your contract.

Pure Error

It also happens. Human mistake. System glitch. No malice — but your problem to fix.

Step 1: Check Whether the Invoice Is Legitimate

Not every post-cancellation invoice is wrong. Check:

What Period Does It Cover?

Compare the invoice period against your confirmed cancellation date. If any of it falls after cancellation, that portion is disputed.

Does It Include Any Legitimate Final Charges?

Final month pro-rata
Early termination fee (if in contract and calculated correctly)
Handset or equipment finance balance
Cessation charges

Does It Include Anything Unjustified?

Service for periods after cancellation
Previously disputed charges that were not resolved
"Admin" or "reconnection" fees that do not exist in the original contract
Services you never authorised (see unauthorised charges)

Step 2: Dispute In Writing — Immediately

The instant a post-cancellation invoice arrives, email Focus Group. Do not phone. Do not pay. Template:

Dear Focus Group,

Account: [X]. I am disputing invoice [Y] dated [date].

I cancelled my account in writing on [date]. Cancellation was confirmed by Focus Group on [date]. [Attach written cancellation confirmation.]

The disputed invoice covers the period [from-to]. Some or all of this period is after my cancellation date. I am not liable for charges after cancellation.

Please provide in writing:

Confirmation that this invoice will be cancelled / corrected

Confirmation that no further invoices will be generated

Confirmation that the direct debit has been / will be cancelled

I will not be paying this invoice. Please respond in writing within 14 working days.

Yours faithfully, [Name, business, date]

Attach everything: the original cancellation email, Focus Group's written cancellation confirmation, the disputed invoice.

Step 3: Protect Your Bank Account

Cancel the Direct Debit — At the Right Moment

If the final legitimate bill has been paid, cancel the direct debit at your bank. Cancellation is instant.

Claim a Direct Debit Refund Under the Guarantee

If Focus Group has already taken money post-cancellation, you can claim a direct debit refund from your bank under the Direct Debit Guarantee. It is fast — usually same-day or next-day — and your bank does not need to take sides in the dispute.

Important: the DD Guarantee is strong. Use it. The provider can challenge the refund with the bank afterwards if they disagree, but in the meantime the money is back in your account.

Watch for New Direct Debit Mandates

Make sure Focus Group has not set up a second mandate under a slightly different name. Check your bank statement monthly.

Step 4: If Focus Group Ignores the Dispute

Formal Complaint

Escalate through Focus Group's formal complaints process. Same written template approach. See our complaints and CISAS article.

CISAS

After 8 weeks or a deadlock letter, escalate to CISAS. Submit all the evidence. The adjudicator can order:

Invoice cancellation
Refund of any amounts paid
Compensation for the inconvenience
Removal of any mark on your credit file

Step 5: Watch for Debt Collection

Some reviewers describe receiving debt collection letters for amounts they had already disputed. If that happens:

Do Not Panic

A debt collector has no special legal power. They can only collect what the creditor is entitled to.

Respond in Writing

To the debt collector:

I dispute this debt. It relates to Focus Group account [X] which was cancelled on [date]. I have already raised this dispute with Focus Group in writing. Please pause collection activity pending resolution of the underlying dispute. I require you to confirm, in writing, what you propose to do next.

Do Not Ignore Court Proceedings

If a claim is issued, engage with it. Default judgements are bad for business credit records.

Document Everything

Every letter, every call. If the dispute goes to court, this is your evidence.

Step 6: Your Credit File

Business Credit File

Missed payments on a telecoms account can affect your business credit rating. If Focus Group reports a missed payment for a disputed invoice:

Raise the dispute with Focus Group in writing
Ask them to mark the account as "disputed" on the credit file
If they do not, complain to the credit reference agency directly

Personal Credit File (Sole Traders)

If you are a sole trader, the telecoms debt may appear on your personal credit file. Same process applies.

The Pattern: Focus Group Reviewers' Advice

From the 1-star Trustpilot reviews, the practical tips that come through from people who have been through post-cancellation billing disputes:

Keep the original written cancellation confirmation safe forever. You may need it 6 months later.
Screenshot your direct debit cancellation — date, bank confirmation.
Do not rely on verbal reassurances that "it's been sorted".
Reply to every invoice, even after you think the dispute is closed — an unreplied-to invoice can become a "debt".
Set calendar reminders to check your bank statement for several months after cancellation.

How to Prevent This on Any Future Contract

Serve cancellation in writing and keep the acknowledgement.
Request written confirmation that the account is closed on a specific date.
Request written confirmation that no further invoices will be generated.
Cancel the direct debit at the right time — after the final bill is paid, not before.
Keep the whole file for at least 6 years.

Frequently Asked Questions

I cancelled Focus Group but still got an invoice — what do I do?

Do not pay. Email Focus Group immediately disputing the invoice in writing, attaching your original cancellation confirmation. Request written confirmation that the invoice will be cancelled and no further invoices will be generated.

Focus Group has taken money after I cancelled — can I get it back?

Yes. Claim a direct debit refund under the Direct Debit Guarantee through your bank. This is fast and does not require Focus Group's agreement.

Can Focus Group charge cessation fees after cancellation?

Possibly. Check your contract. Openreach cessation charges on connectivity are often legitimate. Ask for the charge to be justified in writing with reference to the specific contract clause.

What if Focus Group sends my account to debt collection?

Write to the debt collector disputing the debt. State that the underlying dispute is already with Focus Group. Keep a paper trail. Escalate to CISAS if needed.

Will a Focus Group post-cancellation invoice affect my credit rating?

Potentially. Dispute the invoice in writing and ask Focus Group to mark the account as "disputed" on any credit file entry. If they will not, complain to the credit reference agency directly.
