Airtel — Internet speed and Validity

Hello,
I am Vaibhav Chate owner of [protected] number. I changed my connection to Airtel thinking that the company will provide very good internet services and internet speed. I would like to bring following observations and complaints from my side thinking that it would be resolved at the earliest.

1. I have opted for 4 G speed but when I start browsing the speed is not even matches with 2 G.
2. Recently I have recharged for 1 year on[protected]but validity shows that July2021.
3. There are no platforms for the customer to talk to executive.
4.If a person doesn't have proper internet then how can he complain on Airtel apps?.
5. When I have sent the email to [protected]@in.airtel.com, I got the reply that your email is not register instead of resolving the issue.
