Airtel — Airtel is claiming they are providing 5G, but they are not.

I have been using Airtel since 2016, and my father has been using it since 2010. However, in recent times, Airtel's service has been declining, and the customer care representatives act as if they own the company. In my location, the 5G network is not available. I raised a complaint about this three months ago, but it has not been resolved. Today, on September 11, 2024, at around 11:15 AM, I called customer care, and the representative's behavior was terrible; he even disconnected the call abruptly. I would like to raise a complaint against Airtel for false advertising, and their customer service is consistently unhelpful whenever I face issues.
