Disgruntled Client

When I first signed up with Afrihost for their Pure DSL special, they were very helpful and even when I had an internet issue, they were quick to respond and fix the issue and I completed their agent survey and gave them top ratings. So, for the past almost three weeks now, I've been having intermittent internet connectivity issues, where my connection drops to 0mb/s, yes, you read right. I've contacted them and the one technician has the nerve to tell me to disconnect my devices and reconnect them again, which I knew was not going to work, but I did it anyway, just to have proof it was stupid. I'm struggling to do my work and no one is getting back to me and the intermittent issues are becoming worse. Afrihost is not saying a word as to what the issue is and leaving their clients in the dark. I'm paying for 20mb/s line and at best, I'll get 3mb/s, now and again 12mb/s for 5 minutes then back to 0mb/s. My fiance is also busy with her final year at University and is unable to submit assignments. All this beating around the bush and I still have to pay the full price for a service I'm not even getting half of.

Afrihost, please fix this mess.
