Myntra - Counterfeit product without price tag delivered

I haved ordered Adidas Men Black FLUO running shoe from Myntra online on **th May **** and the product was on **th May ****. When I opened the parcel, to my uttered surprised the shoe box was not of the Adidas brand, but the packed cellotape is label with that of Myntra(caught red-handed), they have cut out the Adidas price tag from the original shoe box and cellotape in the shoe box I have received. When I opened the shoe box, I found a fake Adidas shoe made in Thailand(which from their point of view, even if I return the product to Myntra, it will fail in product quality check, saying local made product. WOW! Myntra, What a cheap way to deceived the customers??) with shoe size UK *, my shoe size is UK *. On top that the price tag was not there inside the box (which I guess from their point of view, even if I return the product, they will not refund the amount due to price tag missing) , instead a shoe tag was poorly attached with a safety pin in one of the shoe. I have been cheated and deceived by Myntra. I want my money back.
