I sent my 11 month old Apple iphone 11 in which was in absolutely pristine condition, was quoted £340 for it. It was securely collected by DPD and after three days of trying to get an update was told that there was a black mark in the camera and the revised offer was £105. I asked for photo evidence of this mark and was told that as I had rejected the offer the photo couldn’t be sent. Also had my email address wrong, so I had no updates, which is helpful. Apparently a known fault with Apple iphones – not anywhere I can find! Although this does appear in Mazuma reviews constantly –and this absolutely screams of Mazuma trying to get premium phones for minimum price. A reduction of £235 for a “mark” which is not evident on any light coloured pictures I’ve taken! God knows what condition the phone will come back in. Would absolutely not recommend.
