Is there any way to bypass the 300gb limit?

I was a VI user and never felt the need to switch to 5G since I had fast Wi-Fi at home. However, a recent storm damaged the wire, so I switched to Airtel. Initially, I installed a few games and streamed some 4K movies, but now the speed has dropped to 0.5 Mbps after exceeding the daily data quota. I recently discovered that Airtel limits data usage to 300 GB per recharge and throttles the speed afterward. Why are they misleading us like this?
