Zivame — zcoins zero after failed transaction

I had rs.1004 worth zcoins in my zivame account which i had received as a refund when i had returned one of my earlier purchases. Today, i tried to make a purchase in zivame, but unfortunately the transaction got cancelled as i entered incorrect password by mistake. Now i see that the zcoins balance has become zero. I have lost rs. 1004 by purchasing on zivame. Tried to contact them but there is no response. Either i need a refund of rs. 1004 or the zcoins back. Worst online shopping experience ever.
