Trendin — Not returning the product... despite guaranteed return

Address:

Gurgaon, Haryana

I have ordered a shirt from : http://www.trendin.com/
My order number is 102511

Since then I have been trying to get return this product.
Every time I call them on customer care[protected], they say that a pick up will be arranged for you tomorrow, but no one comes after that.
I have raised request for return at least 10 times but every time these guys just give the same response that reverse pick up will happen tomorrow. No senior manager is taking any call as every time they say no manager is currently available. I am totally fed up.

My contact number is : +91-[protected]
