Airtel — network related issue airtel

Address:

Bangalore, Karnataka

Airtel claims to have network coverage in bangalore but we never get network inside our home. Even if we go out to call a number we get network but i need to dial 20-30 times a number in order to just get connected,, if at all after so many trails it gets connected in middle connection drops.
The worst part is their service which they provide, i raised a online complain regarding this i got a msg that j will be receiving a call after 2 hr instead of getting call j got a msg conveying that my issue got resolved and they closed the ticket. Who decided on behalf of me that issue was resolved i didn't get.
