Airtel — SMS Service Avail Charge cant send sms using balance left on sim

I had recharged for Rs.49 on 12/07/2021 with gives a talk value of 38.52 and tried to send an SMS, but I was not able to send it, an error was coming. I thought it might be because the Talk value I got maybe a freebie So I had recharged for additional 10 Rs, and still the problem was not cleared. Then I contacted Airtel Customer Care and they are now Saying that SMS can be sent from my sim only if I recharge with an unlimited pack of a minimum of Rs.129. For sending one single SMS I have to Recharge with Rs.129. There is another Unlimited Pack valid for 2day with 19Rs recharge, but that does not have an SMS feature.
Hera I am not saying about an offer I am protesting about the Feature I am denied to have even after payment.
How on earth Airtel is justifying this when premium SMS cost only 5Rs. I agree there are other benefits along with that, but I am not interested in availing those, I am having only 2G network coverage in my area, then why should I go for an internet pack? I as a customer should be on the choosing side if that's not there then why Airtel is running commercials saying they are with Customers?
They are saying TRAI had given the direction that only for unlimited validity pack recharge only sms facility can be given, I dont know who is the head of TRAI, he should be beaten first.
