Airtel — network issue for the past 3 years

I have been requesting about bad network in our area (Anantha nagar phase -2, electronic city, bangalore) for the past 3 years towards airtel customer care. There is no action was taken and they always says the issue would be resolved in 3 months but it never resolved. Current it is very bad situation the signals are still worsen in our area. Due less signal it may draw more current which leads to health issues as well. Truly don't know is this right forum to complaint.

I have been paying around rs. 1000 every month but not able to utilize their services since there is not sufficient network connectivity.

Please do the needful.
