Zivame — zivame zcoins used without order completion

I had 837 zcoins in my zivame account.

I wanted to use them in my next order trying at[protected].
I selected items and filled all shipping address details. And then went on payment stage. On reaching payment step, my zcoins were deducted automatically.

Order was still not completed. Then i had added one more item and again went to payment stage but now it was showing 0 zcoins. So all my money (Zcoins) lost without ordering anything.

I need my zcoins back into my account as this is cheat.
