5G unlimited scam

These airtel bastards. I use an iphone, have an airtel 5g plan for one year. 2999/ year 2gb data per day. My sim is from TN but i live in TS if that makes any difference.

As per their app i am supposed to get 5g unlim data once my daily 2gb is exhausted. So i proceed to use it and exhaust it to see if it works. Surprise surprise, it does not.

So i recharge with 39rs data add on which is supposed to give me unlimited data till midnight. Now heres the real surprise, this doesnt work again.

What kind of scam are these motherfuckers running?
