[Resolved]  Idea Cellular — idea sim card number

Today my mother got a call from my idea number which i'm currently not using but i still have the sim card with me. Also my name is appearing on truecaller. How did the idea company give the same number to someone else which is allotted to me without taking my permission. This is clearly violation of my right to privacy (Included in right to life under article 21 of the indian constitution).
I request the authorized department to take strict action against them regardimg the same.
