Unhappy customer

I am very upset with Vumatel, I have been with them for quite a few months. I have been without internet connection for almost a week now, at first they said it's an outage, they are aware, they sent technicians to come and look at the issue, and saw what the fault it. They promised to come the following day, however no one came, no communication. Today is they 3rd day after they promised to come, I am still waiting. Mind you, I have a daughter who is working from, now is being impacted by this, I'm starting to regret why I signed up with them.
