I purchase a i phone 6 on 18 july 2017 after one month that handset is not working well it show hanging issue so i take that handset to service center. Service center employee reset my phone and say that check the phone but after that phone is not working well same problem occur again so i go back to service center again in the evening of that day then executive say that this handset is screen damaged not covered in warranty you can pay for it. Repare my handset or replace it if it can't repair without any charges otherwise give my money back equal to my phone price according to now days value so can i purchase a new better phone
