Airtel — airtel mobile signal very weak @ ags layout uttarhalli/arehalli area

Hi,
I have been an airtel customer for voice (From year 2000 onwards) past 3 months inside my house the signals are very weak, frequent call drops are happening this has caused lot o[censored]nworkability for me, including my other two members in my family are also using airtel.

I was told by utarhalli airtel outlet (Near chikalsandra) that tower upgradation is going on will be resolved but it is more than 3months there is no improvement.

Incase this does not get resolved iam planning a signature campaign in my layout with more than a lakh of subscribers of airtel to switch to another service provider.

Appreciate a quick response and resolution.

Regards,
Ram
