Paytm Mobile Solutions — Gone s6s phone

Address: 759001

I owned a gone s6s on 24/12/16. After 2 days of delivery of the phone I am Facing heating problem and the battery draining frequently with normal use and also I install a number o[censored]sual applications. Now I want to return the phone, because my first impression was quite disappointing. But I can't contact to paytm regarding this issue. I am trying to connect but still no reply given from paytm support.
