Web Africa
I've tried them all

ISP's in SA are always under fire on this site for bad service etc etc...
I would to say that Web Africa was the best move I've made. I've been with SAOL, Cybersmart, Mweb, Open Web, VoxData and Telkom. Web Africa has by far the most stable and satisfactory services yet. Easy self solutions and very decent response when trying to hold of support.

Thank you Web Africa, I'm fighting with VoxData about bad service at the moment and will be bringing my company's internet needs over to you very soon.
