poor service and lack of response to know issue

When we transfered our telkom line to Afrihost and app**** the static IP......<br> Our 6mbps Service runs intermittently at 0.2mbps, this has been going on for the entire month, I have spent hours on calls and emails to bring this to their attention and they are not able or willing to assist or even call me, they simply send automated responses and reset ports?<br> <br> The issue seems that they are somehow sharing my account somehow and thus sharing my bandwidth with others..... FRUSTRATED
