I used Resolver to get through to Iresa Energy about a refund payment. I had no luck in emailing Iresa even after weeks of trying.So, I signed up to Resolver, filled in all the details, and clicked the send button! Within one hour I had an email from Iresa apologizing and got all of my credit refunds fully paid within two weeks.. It worked for me. Thanks

After 4 years arguing with First Utility about not reading my gas meter, Resolver had it sorted within 2 weeks and the refund soon followed.

Resolver helped me twice - first time to solve the conflict with British Gas and second time - with Euroline. Will use them again.

Took on Scottish power after 2 years of continued refusal to listen to one word I was saying. Amazing support and fantastic outcome, thank you x

Absolutely brilliant website - I managed to get back over £300 that an energy provider owed me from when they went bust well over a year ago. I had had no joy until I used Resolver and now all the money is safely back in my account. It was so easy and stress free. Thank you!
