Telkom email not working for over a week now

I can not send or receive any mails from my [Email Removed] account for over a week now. When you phone , you firstly hold on for I hour plus, then somebody tells you that the email server is still down. They then can not tell you when do they expect the server to be up and running again! They also say that there is no other way to retrieve mails if the server is down! Not poor service! No service! We are trying to run a business here!
