Payment Problem and terrible customer service

I placed an order for a Dell Inspiron today. The money has been debited from my account but I got a message in the payment window saying "your request could not be processed. Please contact customer care' The order is not reflecting in my account either and the product is still in my cart. Your helplines say that office hours are closed and I have received no help or support regarding this. I am very displeased with your service. This is completely unacceptable. Kindly resolve my issue and revert to me at the earliest at .
