legdays in - Return Package delivery not initiated

I got * pants from legdays.in on ** feb ****. Both the pants were not what I ordered. I filed for a replacement for which I was always being ignored all the time. At last after around **days they initiated the replacement. I have given the order for replacement and has been picked up from here, they received exchange order on **th April ****, but still haven't initiated the replacement of my order. I am not able to contact them at all as they have deleted their instagram account on around **th April ****. They don't reply to emails nor do they attend calls nor do they see texts in WhatsApp.. Please help me.. I just want my money back at this point. I don't want the pants somehow I want to contact them and want my money back. I have already given back the pants for replacement and they have collected it too. Please help me get the refund.
