After receiving my product i open it and checked it but my product is not looking gud in condition and return it back on the next day. I got all the messages come from amazon. But my refund not issued to my account. I call so many times to custmer care executives of amazon but no body issued my refund. So i lodge a complaint against amazon for non issue of my refund..
