Myntra.com — refund refused

Address: 641035

When i placed my order it came in a single pack, but when i placed a return request they assigned two separate delivery personnel to collect the package.
When the first delivery guy came he picked up all orders and returned to the facility. After that when the second guy came, we told him that the product has already been returned and he said he will co-ordinate with the other guy.

But now myntra is saying to us that we have not returned that product and they are refusing to refund our amount.

Please help us in this matter.
