poor service from both these companies

I am struggling with Afrihost since Monday to fix my wifi that is slow. I have a 10 megs line and the speed range from .179 to .986. Everyday I have to call and ask what is happening. After they promise to call me back. Telkom called me tested the line and said they will sent some one out yesterday. Today I have no wifi. I called round about 12h00 spoke to a consultant whom were to monitor my line an call me back in a half and hours time. After an hour and a half, I called to find out what is going on. They just don't give a dam about their customers. I am running a business and cannot access any thing without my wifi. If u loose your cool, they tell u no need to be harsh. They get their money every month. They do not wait for it. Why must I struggle to get service.
