Paytm Mobile Solutions — cannot order items from paytm mall

Paytm has block my account from which i cannot order any item from paytm mall. When i place any order from paytm mall so paytm shows that 'you have so many returns of items and our system block your account'. If which product i placed and the order delivered you but the exactly order is not the same as shown in the picture or some times brand was not match so costumer obviously reture that product. Plz unblock my account from which i can order items from paytm mall.
