Airtel — my mobile number has been changed to my wife's g usha vittal name arbitrarily.

Against my application decades ago I have been allotted a mobile number which I have been using and connected to AADHAAR number as well. My name is GN VITTAL. I would like my mobile number to be restored to my name. Approximately a month ago my mobile functions stopped one by one, first text messages were no going but was receiving, next I was neither receiving calls nor was able to make calls including to 121. I contacted on a land line to check the problem. I was asked to go to a nearby Airtel service centre with my AADHAAR card. It was then I was told that my number has been changed to my wife's name without my consent. My number has been in my name and I have been using for all my transactions. I would request Airtel to restore my mobile number to my name.
