I had purchased a ear phone (Delivered on 29 may), however the same was not in working condition. Hence i opted to send a return request on 30th may which was accpted by the vendor. However till date there is no pickup of the item.
The courier partner authorized for the pick up are providing false reasons that they are not able to contact me. Ive already provided my alternate number. Both the numbers are in working condition. Even after raising several complaints the comapny (Paytm mall) is still failing to take appropriate action.

My order details are as follows:
