I’ve had a little problem in my htc one m8 eye but when I contacted htc India, they told me that this product is genuine but they can’t provide manufacture warranty because seller has brought the stock from some other state where maybe taxes are less & bill is of some other state which is a cheating with govt. as seller is making huge profits by cheating the govt. The seller in my case was WS Retail,
I request to seller & htc to resolve this issue asap, as because of this your customers will suffer.
At last, I must appreciate flipkart customer support as my product is under 30 days return policy so they refunded me my amount for a defective mobile(but mind it they will help only within 30 days, after that neither htc will help you nor flipkart)
