Webafrica incompetency

I signed up with Webafrica with great expectations. The router was delivered well in advance and we managed to set it up according to the steps provided on the packaging. Then came the big disappointment. They have no human you can communicate with. When you eventually get hold of an agent on the live chat they're incapable & *********** to assist & resolve a simple issue. We do not get connection but everthingelse is fine. They cannot get us connected. That is all we want and need. They are very eager to take your money & then nothing. Nada. Niks. Can anybody give us advice on how to handle this case, please.
