No show!!

We moved about 3 weeks ago and I requested a transfer of the line quite a while before that! I received an SMS that they will be here that specific day and that was about 2 weeks ago. No show! Not even a call, nothing. I called them again and they said that there is a fault that need to be fixed. Phoned them AGAIN the next week and they said the fault was sorted. I asked them how long it was going to take and they said a week or more. When I ordered a new line with uncapped they were suddenly very eager to come and I received an sms that they will be here, yesterday. They had the wrong address, which is PATHETIC. So the lady just added the right address in the comments, because I am not going to submit a NEW application. They didn't show up yesterday either! I am beyond frustrated at this point. My daughter is in matric and we need the internet for her projects and tasks that she has to do! They don't even have the decency to call and tell us what the problem is. We have to waste our money to call them everyday. It's the middle of the month and we have no internet, so why should I pay at the end of the month for NOTHING?
