i bought a cerifed preowned iphone 5s and the headjacks didnt work. after spending an hr on the phone and driving to corporate store, verizon agrreed and sent me "new" certifed preowned iphone 5s #2. tried to active it and would get a blue screen of death. called and and explained problem, verizon agreeed and sent me "new" certifed preowned iphone 5s # 3.tried to active this and got the saame blue screen of death. Why did i spent 350 for 3 broken phones! Latest solution by verizon is to send me a FORTH certified preowned phone. so upset with the products and service by verizon. "new" phone is set to arrive thursday.....have zero hope that this one will be any different at this point!
