Paytm Mobile Solutions — return denial

Address:

Samlong, Namkum, Ranchi, Ranchi, Jharkhand, 834010

Firstly wrong size was delivered so, I asked qq return which was accepted and product was picked up on 2nd June but on mistake of pickup guy or company they say product was never picked. Even it was confirmed by the delivery guy product was picked that day and sent by him. Company has denied any pickup and refund this total fraud and malpractice by the concerned practice it's almost over week Customer care has come up with any solution even many end up saying that sir product still lies with me. Hereby attaching some proof that pickup guy was on 2nd June to pickup my product.
