Flying Machine — Regarding a fraudulent service

Address:	Bangalore, Karnataka, 560001
Website:	www.flyingmachine.co.in

My issue is that i ordered a shirt from flyingmachine.Co.In website. And i received a different shirt. Moreover the shirt i'd received appeared to be a used shirt and also the price and model number tag of the shirt was not attached when i opened the packing. The bar code and the style on the tag of the wrong shirt which i had received was same as the original shirt. That means someone knowingly sent me the wrong product and put the tag of the original shirt inside. It appeared like a scam.
I called flying machine and sent them email stating everything on 9 june 2016. On 11 june 2016 a courier boy came and picked my shirt.
Today it is 21/06/2016 and i have not got any response from them. When i call them, they just say that it has not reached the ware house. Now its been 10 days the product has not reached the ware house, is it really possible.
I am short in money. I want them to give me the refund.
.
Please help me,.
