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!
Alison via email
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.

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.

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.
Richy G via facebook
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!!!
Vitaura V via facebook
I had an issue with no broadband supply for a month and used Resolver for my claim. Managed to get a refund of the sum paid plus the extra costs I had for paying for mobile broadband until it was fixed. Thanks Resolver!
Daniel T via facebook
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
