Trendin.com — money refund

Address:

Ghaziabad, Uttar Pradesh

i ordered a shirt INR600 via trend in and returned it on April 28 2015. I have been continuously calling and sending them mails, but no steps have been taken from their side to refund my money, even after i told them that i will file a complain in consumer forum. I have spent so much of money in calling them as well as their helpline number is not even toll free. Please help me in getting my money back. It is more than a month now.
