Quikr — Laptop cancelation refund not yet done by dealer

On 11/08/2021 i had taken one of dealer contact from quickr to buy laptop. so i paid 20064 to him on the phone pe no which he provided. but due to some of the reasons i had to cancel the order. he said it will take one month to refund. so i called on mobile no. that he provided for payment but then name aadity kumar singh picked up the call and he said i will refund in one week and i trusted him on that occassion. later on he kept asking me extra money to refund reason being that the product cost is 36000 and gst charges thats what he said .. so now i have paid him total 40744 ruppes ... and he is not responding. he has blocked my number .. take action asap.
