Airtel — number transfer without consent

Address:

Mumbai

This is regarding my number[protected]. Which i am using since 2016 for just banking purpose as it's under my father in law's name which has been transferred without my consent to an other person.

I came to know when i have visited to the hypercity store to reactivate the number where i have found a negitive response from the store that they can not allot me the number. I have explained to them that the same incident was occured in 2017 also.

As been loyal to the company without switching to the network this what's the response i get.

And how can any one claim that he is the owner after 5year.

This indicates that our numbers are not secure. Kindly help for the same to get my number reactivate.
