Unable to get port forwarding working with Airtel ISP

[Gohio]

I finally gave in and agreed to take astatic IP and now they're saying it's 299 per month.
I'm done with airtel. What's the best alternative in Bangalore? ACT?

I am facing the same exact issue. Suddenly my ports stopped getting forwarded since last night. What the frick is Airtel doing!?! I've been using their Fiber for 5 years now but nary and issue but suddenly they decide to put me behind a CGNAT?? Idiots.

Is there any other ISP that offers dynamic IP and/or easy port forwarding? I don't even play games I just have my NAS at home and a Plex server that nearly 20 people use to watch media regularly.
