unconfirmed booking and no refund

Hi,
I booked three tickets of domestic flights of 11,000 INR on 11 th April, 2010 through online Yatra.com. Immediately the money was debited from my bank account though yatra.com was showing that my booking was unconfirmed and my money will be refunded within 72 hours. I have mailed the customer service of Yatra.com several times since it was not refunded even after 7 days. After several mails , I got one reply that they are trying to process a full refund and need my card number to do that. I wonder ,why are they asking my card number, and not refunding it in time. Such a big company with a big name has become a cheater because of its poor customer servants. How people are trying to deceive others. I would request common people not to buy any ticket from this type of travel agents. All of us should get united and complain to court abuot these things and give their emplyees a good lesion so that at least they loose their jobs and die starved.
