Nobody’s perfect, so it’s possible we've made a mistake. If we have failed to meet your expectations you can contact us via live chat in our app or on our website and mention that you need to make a complaint. Alternatively, you can write to us at [email protected]. We promise to try and move Heaven and Earth to make things right:

Sending by post: If you prefer to send us an old school letter with details of your complaint, please address it to our Slice Mobile office:

Complaints, Slice Mobile, 11 Slingsby Pl, London, WC2E 9AB

If sending by post, please provide all account information and one of our agents will contact you by email, call or letter (on request) within 8 weeks of receipt of the letter.

For most things, we will aim to fix the issue in around 5 business days. But if things get a bit technical or more complex, we may need longer as we need time to scratch our heads. We will send you just enough updates so as to not annoy you but still keep you in the loop.

If we can't come to an agreement within 8 weeks, we'll share info on how to reach out to the Communication Ombudsman. They'll look into complaints that are either over 8 weeks old or stuck in a deadlock situation.

A deadlock happens when we've tried our best to address a complaint but can't find common ground with you. If you think your case fits this, you can ask the Slice Help Team handling your complaint for a deadlock letter. But, if we're actively working on a solution, close to resolving the issue, or your complaint isn't under the Ombudsman's scope, we won't send a deadlock letter.

It's important to note that we don't respond to frivolous complaints, and neither does the Ombudsman.

We really hope we can avoid this hassle for you, so please just give us a second chance if we fail the first time around.
