I placed an order on 1 july and my amount was debited from my account then only. but on 2 july info came that order has not been placed due to some problems with payment and if amount ahs been debited will be refunded to me. but till now it hasnt been refunded to me.
They dont answer on twitter and even dont reply on mail. when i called them they told me to wait for another 7 days for them to provide me transaction number of the refund.
