Airtel — No network/service after sim port

Hi,

Yesterday i received the message from airtel that i port request is approved and by11.20 pm my number will be ported.

But at 11.20 pm my old sim stopped working and my when i inserted my new sim i am getting message "mobile network not available", now currently my both sim are not working.

My alternative number recieved the televarification code, but im not even able to call 59059 for activation!!!

I have my online exams on monday the 17th august 2020. Without my sim how am i supposed to write exam??? This is sooo frustrating that im wasting my due to this problem instead of studying!!!

Pls somehow help me out!

My alternative no. [protected]
