tshirtcell com - Wrong product received from tshirtcell com

I had ordered a shirt of Rs. ***/- on **th March **** which was a cash on delivery order and I received it on *nd April **** after paying the amount to the Delhivery courier person. But when I opened the package, there was a different shirt, which was not same as I ordered. Then I tried to contact them via their email address which was Support@tshirtcell.com and then I called them on their number +**-****-***-*** which was not reachable and I also did not receive any email reply from them till date as the email was not delivered as per the Google's Mail Delivery Subsystem. I don't know how to contact them and get refund or replacement. Can you please help me in this regard? Their site address is tshirtcell.com
