Infibeam — Not canceling my order and no refund

Address:	Kannur, Kerala, 670001
Website:	Infibeam.com

I paid Rs 5712 on 12-jan-2016 for a speaker system @ Infibeam.
Yesterday[protected] I have requested for cancellation, but they are not canceling my order.
I did paid the money in advance and I needed a refund as fast as possible, but they are asking for 8 to 21 days for refund . that's after canceling the order .
Why this much delay .
Usually in amazon we are able to cancel an order in sesninds and will get refund in less than 3 days .
Infibeam is trying to rob me ...

I just want to cancel the order and get a fast refund in the credit card that I used to pay.
