Airtel — Airtel show no network after porting to it

I have ported my jio to airtel they told to that the card will be activated by 10pm.My jio Card has lost the network and is now deactivated but the airtel doesn't show any network, my work is getting affected due to this type of service.
I thought porting to airtel would give me better service but now my sim is not active.
Do anything but quickly activate my sim. It's affecting me professionally.
