Airtel — Deactivated Sim Card By Airtel

Address:

At Saharia Purnea Bihar India

Hi My Name is Tohid.
The Airtel deactivated My Airtel Prepaid Sim Card [protected] (Bihar) on 1st August 2023.
I called the customer care but the said please visit any nearest airte store they will reactivate your airte number.
I visited 3 to 4 different airtel stores but they told we cannot reactivate your number.
This number is very very important for me as this number is connected to one of my bank account, aadhar card etc.
Please help how can i reactivate my Airtel number.
