Paytm — Deducted the money, didn't deliver the product, not refunding the whole amount

Address:

Muzaffarpur, Bihar

Hi, my name is Gyanesh and i bought a treadmill online on PAYTM worth 11245 with an offer of 45% cashback i.e. 4000 and to transfer this money to bank account an additional 4% will be charged by paytm which was fine with me. But now they are saying that we couldn't deliver you the product as its out of stock. But when asked earlier about the status, they provided me with the tracking number [protected] via bluedart and the status shown by bluedart is that the product is on hold for some regulatory paperwork. They kept my money i.e. for 20 days till now and now they are saying that we can't deliver you the product but will refund your money. My concern and demand is - 1. I want the product. 2. If the refund is done then I want the whole amount without any deduction.
