Futurebazaar.com — Futurebazaar.com not processing refund

I had placed an order with futurebazaar.com for:
Set of 2 Trek ThumbDrive UDP 4 GB Pendrive
Order total: Rs. 375
Order #: [protected]
Dated: 26 Jan 2012

Order was COD and I was not home when the courier was delivered. The bill with this order was for Rs 825 and that amount was paid to the courier guy since the bill was from Futurebazaar.
I immediately sent an email to futurebazaar at [protected]@futurebazaar.com pointing out that the invoice was incorrect and that I have been charged the extra amount of Rs 450/-. There was no response to the email for 4-5 days and I called up customer service to complain. They took all details and promised to get back to me. No response again for some days so I called again and was told that no complaint was entered in their system. I lodged the complaint again and was told that refund would be processed by 20 Feb 2012. I called again on 23/24 feb since there was no refund made and I was told to wait for maximum 2 more days. When I called again after no refund was made I was told that their systems are down and I should call again, and the phone was put down. On trying again they said that they dont have any update now.
It is quite disappointing and frustrating to not being able to contact anyone senior to resolve this issue and the customer service team has absolutely no interest in helping or resolving the issue expect somehow finish off the call and postpone the customer for a few more days so that when he calls back then someone else will take the call and the cycle is repeated. I have confirmed that they have the complaint registered in their system for the refund and that they do have the correct account details for processing the refund.
