Used to Be the Best, but is Steadily Declining

Email is extremely important to me, so I chose webafrica as a reliable provider. They used to do a good job, but their service has been steadily dropping as the years pass by. Three weeks ago, their server started rejecting my email attachments. The rejection message was clear and the solution simple to a technically-literate person like me. I passed the message on to Webafrica and have had no response, other than a "Our service is not usually this bad" email after about a week. Today, their email service stopped completely - a "cluster board" has failed, I was told when I phoned and after 12 hours of down-time, they have no idea when it will be fixed. If you are looking for a reliable ISP, Webafrica used to be a first-class choice, but they are not good any longer.
