Reliance Mart — Pickup pending and refund not received

I had returned the order but its not picked up yet, it's been 20 days.. I am not getting any correct response from your side, please pick up and give me my money back.I am your old customer but you are giving such bad service.Please try to understand me either you refund me and get pick up whenever you want.

I hope you will solve this as soon as possible..
