Amazon.in — Rejected by seller

Website: Amazon.in

Hi team, we have ordered shoes in Amazon.in and while purchasing they said we can return in 10 days. But after receiving the product the customer care said, we only have to do self shipping.after lot of discussion with customer care, we have done the self shipping. Customer care promised they will return shipping amount also. After shipping now the seller rejected the product, , as they are saying they sold the product through Amazon and they will accept only through Amazon only. We are not receiving the return amount. So pls help us in this.
