In my new sim card with old mobile number, sms is not working. And seems for 48 hrs this is not activated. How to escalate this.

This is seriously impacting me a lot.

First, i dont know, why my sim got blocked? I am a post paid subscriber for last 10 years. I have multiple other subscriptions with airtel.
Second, i ignored, and bought a new sim, for which sms is yet to be activated. My complete bank transactions are blocked because of this.
