Timtara — Not delivering the product not cancelling the order

Address:

Mumbai City, Maharashtra

I had placed an order on the website http://www.timtara.com/ on 31/10/2012 for a mobile handset. Due to delay in delivery, I have tried contacting them many times to cancel the order. I had been trying to cancel the order since 12/11/2012 and have not yet been cancelled yet. Whenever I try an call they they just repeat the same statement stating it will take 48hrs. They have never called me even once after repeatedly complaing on their website and over the phone. Please check weather there is anything that I can do. I had made the payment using my CC and even the bank said they cannot revert the payment.
