Address: 110031

Website: www.apple.com/in

I have gifted an iphone 6 32gb variant to my father on his anniversary in the month of april. But it turned into family headache it got replaced once but now its more pathetic. Its gets stuck, working so badly, when it requires a lot application stops responding. Apple is worldwide known brand but its making chinese quality product and after sales service is no where. I request your support to get this pain refund by company or replaced with upgrade model. Serial number:fdpv316qhxr5 imei :[protected]
