Quikr — Nikon d5600 dual lens kit.

Last Wednesday ( 3/11/2021) I deal with quikr for Nikon D5600 dual lens kit. Offered were made was ₹5800 for the above mentioned product. I paid them ₹5800 on that same day. Later on they said to pay Custom duty, delivery charge, Nikon insurance. I paid them. They told me that I will get back my money for this after I receive the delivery. After one day, the account team (as per they said) called me and told that to get back my cash back you have to pay the total money. I paid them that. And now there are not sending me the product and the cash back also. I want my product and as well as the cash back also. I will not pay any single amount.
