If something has gone wrong, we would like the chance to put it right. This page sets out how to complain and what happens next.
Contact us with your name, contact details, what happened and what you would like us to do about it:
We can only deal with complaints about our own service. If your complaint is about a network's billing, coverage or contract terms on an account you hold directly with them, it must go to that network, because we have no access to it.
If you have complained to your network and are not satisfied after eight weeks, or you receive a deadlock letter, you can take it to an Ofcom approved alternative dispute resolution scheme. Your network will tell you which scheme it belongs to.
You can get free, independent advice from Citizens Advice on 0808 223 1133 or at citizensadvice.org.uk. Nothing on this page affects your right to take legal action.
