Amazon India — bulfyss chrome steel pull up adjustable gym bar with cushioned grips (64-100 cm) asin: b01eo93rei

I have ordered bulfyss chrome steel pull up adjustable gym bar with cushioned grips (64-100 cm) asin: b01eo93rei which was returned on 18.6.18 by return order no.[protected]. The company was refunded the money on wrong ifc code and now stating that that are not been able to process further as their billing section is not able to do it, and i have not been paid the refund amount of rs. 519 of the above said item. Nor solved my problem. Very poor refund process of amazon india. I just wanted to know if the money is not refunded to the concer party, it is not the duty of amazon to find it out where it is hanging.
