[Resolved]  Airtel — Owner ship wrong entry & signal lost

I am using airtel sim from 8years ([protected]). Suddenly signal lost 1week before. I tried to talk with customer care. They are not solved problem. I went to offline store. They said need proofs. I gave my proofs. They are saying owner is different person. They said need that person proofs. They entered wrong details when I took sim may be. I connected my alll banking and all stuff with that number. It's very important to me. Airtel is not help and not investing anything about it
