Airtel — Airtel Sim NO service very unprofessional

Hello Sir,

I need your help in resolving the issue, I stay in UAE and have an Airtel India sim for all my banks' and tax filing purposes, I have had this number for more than 10 years. I have an issue with Airtel services, I have recharged for a year plan like I used to do every time, and have a balance of more than 900 INR yet my sim is deactivated and shows no service now. Luckily I had my father in law visiting me so I sent the sim with him and on his inquiry, now they say I need to be physically present to start the sim, this is unreasonable, and I don't understand why did the sim was deactivated even with an active package and a balance of 900 INR and this has caused my payments to insurance and all other services back home to be stopped. Please help me in this regard,
