Bad service - signed up and still no internet

Signed up for internet 2 weeks ago. None of the agents at Afrihost seem to know what’s happening and definitely do not have the capability of facilitating between Vumatel and us. This is very frustrating. Don’t even require an installation. Vumatel people pitch up at the house without warning while we are at work. Then after arranged for a better time, they don’t pitch at all.
