BSNL Broadband
No connectivity for longer time & slow speed

I have ul750 broadband plan of bsnl dataone. In sangamner there are lots of people who used this servies. But when we connect to the internet it gives error "the phone line is busy"

hence we are tried for longer time this error shown again and again.

And company provides 256kbps to 2mbps speed to us but thre is ony 28 to 30kbps speed. Its a bore servies of broadband

but they do not returns deposite & don't exchange modem worth rs 2000 (Modem=1200 rs deposite=800 rs)
