SHOCKING INTERNET SPEEDS and broken promises

For the past two months I have experienced absolutely shocking Internet speeds on my Afrihost 2Mbps Uncapped ADSL line during the evenings and during weekends (i.e. peak periods for Internet use in the Dainfern residential area).<br> <br> I have submitted multiple complaints via Clientzone and called the Call Centre on three occasions. Everytime the operator either says they're reset a few things, restart your router and it will be fixed (and it only is fixed for a few hours then it's back to the poor speeds again) or the operator (specifically Pita or some version of Peter) says they have submitted a complaint with Telkom and the Telkom department of Afrihost (as my line is managed by you guys too). Unfortunately for the last two days someone from Afrihost or Telkom hasn't as promised by Pita two days ago. He promised to get back to me but he still hasn't even though I asked him if he's sure he'll get back to me and he assured me.<br> <br> Absolutely shocking service! I would like to cancel my service with Afrihost with immediate effect and move to another ISP. If Afrihost can assist me in this regard that would be much appreciated!!
