On 3rd September 2015 I bought the iphone 6 plus which was quite expensive for a mobile phone but I thought it would be worth it. In a month's time it bent, all of a sudden. The telephone has no damage, it functions perfectly but it bears a small bend which it is obvious that no human hand could do it. I sent it to my carrier here in Greece (Cosmote) and they asked me 370 euros to fix it. In Greece there is no apple shop where I could actually go and talk to an apple expert, so could you please advise me what to do next??
