Pathetic customer service

I have my adsl line and uncapped business adsl with afrihost. For the last couple of months I have been struggling with my connection. I would work, download or stream and then all of a sudden my ping would drop to 2500ms and my dowload would fall to below download speed.I reported this to afrihost in april. They logged a call with telkom. Then nothing, no feedback, nothing. The line would continue with its up and downs, but every now and again it would be stable. Last Friday it just went down hill. I reported it 3 times to Afrihost, as they never answer their lines. Today, I phoned twice, held on for 13 minutes, only to be cut off. Then phoned back, held for 8 minutes, then cut off again.I have not had a single piece of feedback from them on any of the issues logged. I checked the telkom website for the fault they logged. And got a message that it has been resolved. What has been resolved!!?? I am fed up with this pathetic service. I want my money back, which you guys are pretty quick to take! You are suppose to manage my line, as well as the issues logged on that line. Else I might just as well leave the line at telkom!
