I have complained to airtel - Bangalore many a times, but it seems no one is dedicated to provide any proper service. Last time when I had the conversation with airtel executive 2-3 month before she told that issue will get resolved in 2-3 working days. but nothing ha-penned till date.
I am getting very poor signal from airtel in the AECS Layout area, Bangalore . Also everyone who stays in that area is porting their number to other operators. But it seems airtel hardly has anything to do with the complains.
Their charges are much much high than any other service operator in bangalore and service and customer support I as worst as it can be.
