Airtel — airtel poor service since 6 years+

Address:

Hyderabad, Hyderabad, Telangana, 500094

Respected team,

I am a very loyal customer of airtel for the past 10+ years. I have 7 postpaid connections of airtel mobile phone since many years. I have a great opinion on the service provider. Unfortunately, this seems to be a blind belief on them. I am living in kukatpally area in hyderabad. I appreciate the signal width of airtel even in remote areas but for the past 6 years i cant get signals in my home. Including old aged family members at my home who are 70+ need to go out of my house to take call or talk to someone. We as youngsters can do it but i see my parents being unable to go out sometimes. We are missing important calls. More we call customer service to resolve the issue, the more it doesn't work. They always say they have optimized the nearby tower but nothing works.
We are patiently wanting them to resolve the issue because airtel provides best network coverage all over india.
I feel bad that it is failing to look after what could be our problem. They say they tried to reach us, but when there are no signals in our home how is it possible for them to talk to us?
I am fed up with the service. I want to use airtel as network provider to my whole family, but it seems it's waste.

Please help me to resolve the issue.

Regards,
S. L. Bhavani
