Club Factory — return is done but I have not received the refund

Address:	Gautam Buddh Nagar, Uttar Pradesh, 201301
Website:	club factory

I have placed an order as a guest user and they have send me wrong size so i returned the product once they received the order they are not refunding the money which is of almost 2000 rupees. Every time i ask them they are saying the same thing check ur balance which is showing 0.00 usd in my balance.
I m continuously saying that i have looged in as a guest user but they are denying to accept. I even ask them to send in my paytm account but they only talk on chat n dont reply properly and when i called then they deniyed to hlp. I just need the money orelse i m filing an fir against this company and going to count for mental harassment as well cz it has been 1 month i m asking for my money but i m not getting.

Such a cheap company i will sue them i swr.
