Incomplete installation and activation.

I have waited for almost 3 weeks to get an appt for installation. Constant calls to you guys, rejection of my order multiple times for no reason that you can provide. Finally when I got an appt the guys came to install the line and did not connect and activate it!!!!!! I was then promised and certified by the installation guys that someone would definitely come to activate the line the next day. NO ONE came or even called, I then have been calling your call centre, NO ONE is helpful or can say why the installation has not been completed and when the soonest possible time someone can come to activate. It is SOOO frustrating now waiting again for another week. This is disgusting service and unprofessional. I am Paying for something that I don’t even have!!!
