ZeeNext Broadband - Joke of the era

In Byrasandra, Bangalore my ZeeNext broadband connection is down every alternate day. And after midnight, you are not able to ping the gateway and the connection dies out. No use calling the ZeeNext Customer care as they seems to lack the basic knowledge in understanding the problem. Am sick and tired of shouting the BB101 error code to them every day.. All you hear from them is sorry will resolve this is 12 working hrs.. No way, ZeeNext sucks big time..
