Myntra.com — Puma shoes

I ordered puma shoes for 1799, it was an used product as the price tag was also not intact.
I placed return request and the pickup guy denied to take the item and kept the return on hold and asked me to talk to customer care.
I raised a query in customer care and after some hours costumer care resolved my query saying their item was not used and passed all quality check.
This item is myshoesize+1 in size.I can't even use this.
I want my money back.
