[Resolved]  Lenskart — Return order picked up but no refund

I applied to return order no 12215386 on 15 july, 2020 and it was picked up on 22nd july. But i got no refund. I gave the eyeglasses to the man who came for pickup but i recieved no message that order has been picked up. I have been calling lenskart custome care since then but they say courier company has made no such pickup because your registered number was unavailable when they called. This is such an absurd thing to say as they have been calling on the same number to sell their other products. Also, even if my number was not available they know the address why they had to call and then only pickup the return order. It has been a month now. I want my money back. I can't pay for their carelessness.
