Airtel — outgoing calls & sms are not working

Address:

641043

Hi sir/madam,
My airtel prepaid number is [protected].
For past 3 months am facing a problem in outgoing calls and sms.
Not even a single call or sms is going for me. Call gets disconnected immediately after dial-in i visited nearly 4 to 5 airtel customer service centre they are not able to fix my problem. I tried sim swapping for 3 times still issue persist. Could you please fix this problem for me. It would be great if you resolve my problem asap.
Attached a video for reference.

Regards,
Sundar r
