Meesho — Not received my refund

I ordered a saree from meesho app. They were not the same as i ordered so i returned them. I made online payment for theorders. After returning the parcels they processed my refund from their side and told to wait for 5-7 working days for the credit to reflect in my account but its been 1month but there is no amount credited. I made conplaints with my bank and also with meesho customer care but no response from their end. The order ids [protected] amount is 685. I have been approaching everywhere to seek help but no resolution from anywhere. It was completely your mistake for getting my refund. Because the delivery person did not give the pick up slip which is completely not my fault . Even after so many calls to the customer care there was no solution I want my refund amount total amount is Rs.685/- which is not a less amount
