Bad service

Place an order with Afrihost and from the 30th April to the 8th May, they have not sorted out my WI-FI, I message them daily but no one seems to know what the hell they doing. All they say I am sorry for your inconvenience, how is this supposed to help when I am working from home. To pay for a service that does not work and you end up not speaking to them directly even when you asked them to get a supervisor to phone, but it is too much hassle to get someone to phone me. All I want is that my Wi-Fi/Internet to work.
