Dealinmart.com — refund of money

Respected sir

I placed an order on 26/10/17 to dealinmart.com i ordered a redmi 4a. The order got cancelled on 10/11/17 and i was told to send my bank account details and that the refund will be initiated in 10-15 working days. Its been more than 2 months and i have not yet received any refund. They do not attend calls or emails. There is no way to contact them at all.
Kindly do the needful.

Thanking you
