Airtel — no network available indoor and outdoor

Address:

Embassy tech zone Mississippi building Hinjawadi phase 2, Pune, Maharashtra, 411057

I have recently switched my network form idea to airtel due to slow network issue since i have changes my network to airtel problem is more worse i couldn't even get ant signal indoors and very slow network outdoors. I cant understand what kind of network is this and the customer care executives ask me to be patient issue will be resolved they cant understand the severity of my issue its like i am being without a mobile form past 4 days. Im unable to port to any other network now as its been only a week i have switched.
I want this issue to be resolved in a couple of days or else only option left with me is to throw this sim and take a new jio network. Hope someone will respond fast and resolve this.
