I sent my blue iPhone 13 pro max to them, they then sent a offer for a phone that wasn't even mine, a sliver iPhone 12 pro max. They then told me I had to prove this wasn't my phone, I gave them my IMEI number and was told they had not received my phone as it wasn't on their system. I then provided proof of delivery, as I sent it special delivery, this showed a picture of the phone being delivered and the person signing for it. They then said they would need to look in to this. a few hours later they had found it and came back with a low ball offer for the phone (from £425 to £310) the phone was clearly worth more than this. But as other people have said, the phone comes back in a worse condition that when sent, I reluctantly accepted. All the above stress and aggravation, only to get a low offer and no offer of compensation for all the trouble caused. all of which was their fault!!!
