D-Vois Communications — customer service

First of all its false advertisement in their ivr. Best customer service it seems.
I complaints almost 2 months back as one of the guys abused me on the call because i was persistent to get my internet working asap.
In multiple occasions they have refused to transfer to supervisor upon asking which ideally you can't do as per what i understand because i come from same field.
The internet has issue every now and then and even if the local engineers at office are available they won't help after 7.

I hope at least now i would get some help
