bought a second had iphone 6 from a CEX store. I had it for 6 months and then one day it stopped turning on. I took it to the CEX store with all of my receipts and was told they could not try to fix it or refund the warranty because it had been water damaged. While in my possession, the phone never got wet and was not taken into humid areas. I was very careful with the phone because I do not have enough money to purchase another one. I found the absolute refusal of the staff to help as unacceptable, even if the phone had somehow been water damaged it is clear that this did not cause the phone to break. I will never shop here again - I lost over £300.
