When You Can Escalate
6 weeks from first making the complaint, or earlier if you receive a deadlock letter (complaints made before 8 April 2026 had an 8 week wait). Source: Ofcom, CISAS and Communications Ombudsman pages. Scheme: CISAS (Communication and Internet Services Adjudication Scheme). source
Your Contract
Information Before You Sign
Before you are bound, residential customers and small businesses with ten employees or fewer should receive a written one-page summary of the contract (three pages for bundled services) covering charges, contract length and how to cancel, followed by the fuller written contract information. source
Changes to Your Terms
Providers can change contract terms, but they must give at least one month's notice, and you have the right to leave without penalty if the change does not benefit you. You cannot leave over changes that only benefit you, are purely administrative or are imposed by law, such as a VAT change. source
Time Limits to Know
Miss a deadline and you can lose a right. Check the dates on your own paperwork.

Complain to Vodafone in writing using the route below, and ask for a complaint reference. Say what went wrong, what you want, and by when (14 days is reasonable). Our free letter templates can write it for you.

Where to Go If It Is Not Put Right
Your options, in order, and when each one applies. All are free.
Vodafone Complaints
Always start here, in writing.
CISAS (Communication and Internet Services Adjudication Scheme)
After 6 weeks, or when you get a final (deadlock) response.
Your Card Provider
If you paid by card, Section 75 (credit card) or chargeback (debit card) may help.
Citizens Advice Consumer Service
Free advice. It can pass a report to Trading Standards.
Good to Know
Small things that make your complaint stronger.
Complaints about financial products (such as a loan or insurance) go to the Financial Ombudsman Service instead.
Keep speed test screenshots and note the dates of every fault report and call.
Ask whether you qualify for compensation for a delayed repair, missed appointment or loss of service.
Check your contract if you want to leave: you may be able to leave without charge if the service is not what was promised.
