Airtel — Airtel sim not working after porting

I ported my idea number to airtel on 24/09/20. And on 27/09 my idea sim was inactive and i put the airtel sim and it worked fine. Then i checked for the balance and i found only 5₹ and 300mb 2g.
Then i called the store and they recharged.
After that when i checked my airtel sim is dead.
Now i dont have a sim.
Im fkin frustrated now.
Do something.
