Vodafone India — Recycling of numbers without notifying the customer

Address:	Bangalore, Karnataka, 560077
Website:	vodafone.in

I was using vodafone number for past 2 years and recently moved to united states and was still using the number to get OTP and other incoming messages. I was using it until december 2015, and in Jan I realize that my number has been allotted to a different customer without notifying me by any means. I should have been notified well in advance before taking such an action. This is serious security lapse as all my OTPs, and other personal information would go to a stranger.
