Timtara.com; Product - HTC Salsa — Non refund of money after cancellation of order

Address:

Khordha, Odisha

I ordered for a HTC Sala mobile phone which showed "in stock" and paid the full amount then only which was a sum of approx Rs.13,000.It was in the month of November last year.The product didnt came and I cancelled my order.
Now on asking about the refund of my money,they say "give us a week time and we will solve your issue".
It has been almost 5 months,I havnt got that huge sum of my money back.
I am enclosing a conversation mail between me and one of their representative.
I want some strict action towards them asap.
