Zivame — refund issue

I ordered bra from zivame.com but later cancelled it due to delay delivery. I got refund as z coins. It has been mentioned there if you want to transfer the money into bank account contact customer care. From last 2 days i am continuously trying to contact customer care but it was busy all the time. I want my money to be transfer into my bank account.

I also raise ticket with zivame but no response
Really a worst site for shopping.
