When I asked their support. They told me that the transaction needs to get confirmed. And I told them that it already has 6 confirmations and it is unreturnable at this point. And they answered that it is not confirmed at their end. 
I told them that if a transaction is confirmed at one end, it is confirmed everywhere. And they told me to wait an hour.

That's the problem with most customer support where the employee doesn't have technical knowledge and only know how to solve common problem.
Wait what? They track an individual's payments based purely on TransactionID? 
That seems like a recipe for disaster!!?! And also prevents users from using RBF etc
