BSNL Cellone — Get network busy or call drops in my 2 bsnl numbers

Address:

Bangalore, Karnataka

Hi, I have been filing complaint since last 2 months. I get network busy most of the time, or call drops or only I can hear the conversation when I use [protected] or [protected]. It is more in my house or outside lane of my house. But it also happens anywhere in Bangalore when I am moving especially in Bellandur. I have raised around 25 complains to cellone online grievance system in last 2 months. Regards Manish
