[Resolved]  LazyPay — Unauthorized debit and denying to refund

I made transaction using lazypay on myntra, payment debit in lazypay but same was not reflected in myntra. so i cancelled order.

But when i called customer care of lazypay they said they cant refund money unless they get written proof from myntra. But this is never happens no merchant gives such things since everything is on system and it is clearly seen that myntra didn't received amount and the executive also admitted yes myntra didn't receive the money.
