Uber — Blocked account for no specific reason

Address:	Bangalore, Karnataka, 560029
Website:	www.uber.com/en-IN

My Uber account has been blocked for a long time. I have repeatedly requested Uber to tell me the reason for blocking my account but their only reply is that their system does it for security purposes and that the system could be wrong. I haven't gotten any response stating that they will unblock it or look into it. They won't even tell me the reason my account has been blocked. I need to know why they have blocked my account and unblock it.
