Paytm Mobile Solutions — My account got merged by mistake

Address: Bangalore, Karnataka, 560040

My registered mobile number is [protected]. I ordered men's purple blazer. Order id [protected]. After that my account got merged. So I had to return that blazer but there is no order list in my mobile because all order list got merged. So after that I mailed to paytm after that they sent a courier man for return pick up. Courier man took the product. After that I got message from paytm your refund amount 1579 is successfully. But I am not able to see that amount 1579 in my wallet. I can see zero. It almost one month over. Till I didn't get my money. I have mailed so many time. I called paytm so many time. But there is no perfect answer from paytm. Please resolve my problem. How can I get my money 1579. Please paytm.
