Airtel — airtel poor 4g data connection and voice call reception

I am unable to use internet using aietel 4g data connection. From sep2019 onwards i am being told that there is new tower is coming up and this problem would be resolved. But till now there is no progress. I have paid rs.480 for 82 days 4g data connection without using internet and voice as poor signal. And again 5th dec 2018 till now i rarely use interenet and voice call as the poor signal. It force me to think to switch over to other service provider. I purchased bsnl sim for voice call because airtel poor connection.
