Transdeals.in — money is not refunding

I got a call claiming that they are calling from rbl bank and they are offering discount card based on my cc transactions. They said i will get 20% off on everything wherever they accept visa debit/credit card.

Their company name is transdeals currently using the name deals way shop, they are the no. 1 well established fraud company. They didn't tell their company name until i made the payment of rs 7899 via online. They did not allowed me to think and kept pushing me until i made the payment.

Only when i received the kit, i realised that this is not from rbl bank...
Please refund money. I have already requested them but they are not even listening anything.
