Bad service and slow connection

I app**** online for fibre connection on the SADV line in the complex on the 1st November, and I was told that the connection would take 2-3 weeks, however, I'm still awaiting a phone call to setup a time for the connection. It's over a month now and no connection is done. The service is really bad as I do not get any update or feedback on the status of the connection. Every week I have to follow-up to hear one excuse that SADV has been notified, they will call me. I placed the order with Afrihost and not with SADV. I want to cancel my order and move to a better ISP. This service is really disappointing to say the least.
