Afrihost is beyond terrible service

Afrihost is the worst internet service provider that I have ever dealt with. If I could score them below Zero, I would. I have signed up and is paying for 100/100MB fibre line for the last few months. From day 1 they could not get to speeds even above 70MB. They have a whole lot of excuses why I cannot get the speeds I am paying for. In the lasts few weeks I am not even reaching speeds of 20MB. When I call them or do a call back I am helped by different people and all havs their own explaination and excuses. Currently VUMATEL is being blamed for the slow speeds I am experiencing. In the meantime I cannot anything on more then 1 device. I will never recommend anyone to get afrihost, there service is beyond terrible.
