Worst customer service experience I had. Every customer department uses different system and most of them do not write notes, we need to keep repeating the same information to everyone and still people do not try to help. I upgraded 2 phone, received 2 faulty iphones, returned them 1 week ago, received call from warehouse that phone has been returned, royalmail tracker shows phone has been returned but customer service has no information about return. They advice me to call tomorrow everyday I call them. I wish, I never renewed my contract. They know how to frustrate their customers and waste their time.
