Amazon India — No refund even after filing calling customer care

Address:	560066

I have placed an order for "Fox Raptor1 Motorcycle Racing Knee/Shin Guard Pad (BLack, Set of 2)" on 25th Feb. However after finding cheap quality I have returned the product. Product is been returned and reached to seller as per confirmed by the seller.
But I didn't get my refund till March end. So I called customer care and they assured me the refund within 5 days.
From then I have called 2 more time and every time they assured that refund will be done within 5 days.
Today is April 25th. Its almost 8 weeks since I have returned the package. Still searching for my refund.
