Airtel — Misleading and unethical behaviour

I heard from my friends that Airtel 5G service has arrived in our area and 5G was also showing on everyone's phones. And these people claim to provide unlimited internet on using 5G. So that's why I ported my SIM from Vodafone Idea to Airtel on 1st November. On 4th November, the phone got network and is also showing 5G but when I used internet, my 4G data started getting exhausted and due to which I came to know that Airtel scammed me by just showing 5G while the internet is only on 4G. This means that Airtel is just misleading the public by falsely promising them unlimited 5G. This has caused me financial loss and also inconvenience.
