Dropped offer from ?220 to ?50 on the basis that the button wasn’t working. My phone didn’t have a button. Had expected them to drop quote a little but thought unreasonable for a very well looked after device.Received back (although with accessories and box missing) and sold for a decent amount no problem at CEX where it unsurprisingly passed all tests.Updated after UR response- they asked for further details which I have provided. They’re not disputing anything I’ve said.
