Meesho — Received Wrong Qty items, No refund

We ordered 2 Qty, But received only 1 Qty.
When we placed for the return pickup, The return pickup person has come, he also agreed that only 1 Qty can fit it into the cover. But we received the refund for only 1 Qty.

When we called the customer care, they have taken the complaint and asked me to wait for couple of days. I waited for 1 week, then called customer care, then they are saying that "I received 2 Qty and returned 1 Qty".
