Meesho — Product Picked up but they have not refund

I requested to return product, They picked up product from here but not updated status, but they send one more guy to pick again and he updated status as Reverse pick up cancelled and have not refunded amount yet.
I complaint many time to customer care but they always says wait 24/48 hours. I dropped mail also them with the message which I got after picked up item, but still they are not responding on that.

Please help in same.
