I have a account in amazon... Few days back they had released offers page in their website i tried to book a product during the offers but after adding my gift card nd procced to check out i got to know that my account is blocked i tried to contact customer service to solve issue but the customer service said even they don't know why my account is blocked i tried for more days i was keeping to call customer service but they dint respond they cutted the call i waited more then 7-8 days... But i was getting a mail that they we asking unnecessary details for unblocking... No one contacted me to solve issue during offer i was trying to book products by that time my account was blocked during offer but after offers end today i got mail that ur account is unblocked u can use it... After offer ends how i can use it now they wr cheating customer saying that gvng offers nd blocking there account is thz the way to give offers.. I attached my details of booking nd. Unnecessary details asks from amazon.. Please take serious action against this... I tried from 8/8/17 by that time offer was gng on..
