Airtel — SIM deactivate: Request for SIM is not addressed by Airtel

I have been using AIRTEL number for a very long time. I recently moved to the US with an airtel roaming facility. However, the SIM stopped working and I am unable to access any of my linked accounts. I have been in touch with AIRTEL but they are unable to help.
All my IDs and Bank documents rely on this number and I am almost helpless in accessing any of them right now which is frustrating.
Please provide me with an option.
I am desperate to activate the number. I am unable to access my GPAY, bank or national IDs.

How come AIRTEL is making me so helpless?
I have been a loyal customer for a very long time. This is very disappointing and especially when you are overseas.

I have been writing to them and contacting via email ([protected]@in.airtel.com; Content.[protected]@airtel.com), WhatsApp (AIRTEL CARES) and over phone. Everywhere i get no response.
