Reliance Trends — Refund payment fraud

Address:

Daund

I have bought the clothes on 6 aug in trends near to me in daund
Some items are retuned to them but they refused to get it refund due to their policy. So they added the refund value around 1500 rs. against my mobile number and asked to redeem it whenever I come to shopping..
They have sent me system generated masage for same .But unfortunately the masage got delete by me
When I go for shopping and ask to check refund amount or redeemed point but are not aware the things I told to them, as whole staff got changed.
Now they are not ready to help me on that.pls help me
