After I moved from Delhi to Bengaluru in April, I have been using 2 connections of Airtel. I stay in JP nagar 7th phase and almost 50% of the time, my call gets disconnected within 1 min. When I complained to Airtel in the same month, they kept it open for more than a month. When I contacted them later, they had closed the complaint without any resolution. The guys told me that they had visited my place and since I was not around, they did a survey and found everything is okay!
When I protested, they opened another complaint, which is open for the past 4 months. Every time I remember I call them, only to get the same answer. "The complaint has been forwarded to their technical team and they would call me in next 3-4 days". That "3-4 days" is yet to come.
I am not sure which is the other service provider I should go to. Anybody can tell me if BSNL or TATA is better in coverage. How is their service?
