I sent back a Phone 5s in good working order. It had no issues and always had a protective case and and screen protector on it. They offered £25 for it and that was fine. I have just received an email saying the screen has a problem and needs to be replaced? Total nonsense. It was in perfect working order. After looking at the other reviews I’m seeing a pattern here. They quote and you send them the device. When they have it they then contact you and claim it has issues and you accept a lower cost. This is something I’m going to talk to trading standards about.
