Dell India — Not Refunding Amount

I tried ordering Dell business Laptop last week[protected] .
During the payment process, the amount got debited from my account but unfortunately I didn't get any order confirmation message.

On the same day[protected], I dropped an email to indiaconsumer.[protected]@dell.com and they have asked me to wait for 48 hours.
After 48 hours, I didn't receive any update and I kept following up with them but no proper update, so please help to refund the money so that I can order a new consumer laptop.

I have been following up daily and all I get is to wait for 48 hour.

One week has been completed, till now no progress.

Below are the email ids, i have been following up, but no response.
