Zebpay — failed deposit

I transferred rs. 20000 on march 12 to zebpay via neft. The amount shows debited from my account but the transcation comes up as failed in the zebpay app and there is 0 balance in my account. I have opened few support tickets but there has been no proper reply from zebpay support. They keep saying that they are looking into it.
It has been 2 weeks, and my account hasnt been refunded the money. Please look into this issue and have it resolved.
