Very poor service regarding installation and feedback

MWeb was fast to subscribe me for a new service, but there it stopped. Their installation team came to install the fiber line to my house, however, they could not get it working and promised to return the next day to fix the problem. It is now 3 weeks later and no further news from them. I contact them day after day, spend an average of 45 minutes per day in the queue to speak to someone. This person then make a promise to follow up and give me an update. This never happens and I end up i the queue again. My last effort was on 29 Jan 2018 when the person at the call center effectively told me to wait until they get to me. I asked to speak to the manager. I was put in contact with Widaad, who promised to follow up and call me on 31 January 2018 to provide me with feedback. Widaad did not keep her promise, so today, 1 February, I spent my 40 minutes in the queue again and eventually spoke to Linda. Linda promised me that she would make sure that Widaad calls me back today to give me feedback. Now it is wait and see - from past experience I am not holding my breath. When asking for an email address, to avoid me sitting in the queue again (due to MWeb's non performance, Linda refuses. In other words, absolutely no respect for my time. If it goes like this now already, what is going to happen later......?
