Meesho — User validation failed

Address:

Hinjewadi phase 3, Pune

I had ordered 6-7 products from meesho, I have been a customer since long time so did not think that some fraud can be done. 2 orders got delivered, and one is completely different. I ordered salwar suit and a torn hoodie type tshirt is delivered. As soon as I opened app to return it, the msg popped up saying user validation failed. When called to customer care, they said nothing can be done.
