Three complaints

Three has decided not to accept complaints raised via Resolver. As a result, the Ombudsman is unable to consider complaints raised with Three via Resolver.

We think this is a shame, as we are believe consumers should have many options to access support when raising their issues. However, if you decide to use Resolver, you'll still be able to access our rights guides and template letters to assist with your complaint.

Please contact Three directly in addition to making a Resolver case. We are sorry for the inconvenience.

The tools make it really easy to raise an official complaint. I escalated the complaint explaining that all of the conversations were being logged on the site. They settled my complaint very quickly after the escalation. I highly recommend using this site to complain if you've hit a brick wall with a company.

After a £600 bill from Vodafone and getting nowhere on my own, by using your service, I was given a full refund within 3 days as well as having my tariff reduced. I wouldn't have been able to achieve this outcome without Resolver.

O2 have seen sense and released me! Pretty sure it's down to Resolver, so a big hi-five your way!

O2 have agreed to refund the erroneous charges they made.... I got my money back, so happy, and very impressed with your website!

Wow! Thank you so much. I emailed a retailer for a refund on headphones that were never delivered, over 20 times, yet had no joy. As soon as Resolver got involved I got my refund within hours.

Resolver got cracking on my case really quickly. The following day the retailer I had an issue with was in touch and just a few days later I received a full refund. It was much easier than I expected to set up a case with Resolver and you can add to it later. Highly recommend Resolver, brilliant company to have on your side

Best way to deal with mobile network providers. Been trying to get my PAC off one for maybe 6 months. With the help of Resolver I received it in less than a week. Would definitely recommend!!!

Absolutely brilliant! Got a replacement and refund for a microwave fox from a store, without a receipt or proof of purchase!! Very impressed with both companies

Read and understand your consumer rights then answer a few simple questions to help Resolver prepare your email (which you can review and edit) that clarifies the issue, and gets the best from your complaint.

How does my Three case file work?

Resolver allows you to keep a record of any email correspondence sent between you and Three, as well any phone calls made via our mobile app. You can make private notes about your case as well as set yourself reminders. Furthermore, Resolver sends you notifications when it's time to escalate your case to help keep things on track. If you cannot resolve your complaint with Three, Resolver enables you to escalate it to the relevant regulatory body – the contents of your case file is sent as supporting evidence.
