Link down, poor customer service, billing in full for service not available every month longer than 4 days

I have taken a fibre link from Afrihost through Vumatel from October 2017 and ever since we took this fibre we go down every month for 4 to 5 days and Afrihost bills us for the entire month even though we dont get to use the service fully, Every time we go down no on even monitors the link and calls us to log a fault we got to call in log a fault, i am absolutely disgusted by the service we get from Vumatel and Afrihost, i have requested on several occasions that a manager contact me as i am unhappy and still to date no one has called me, In March we spoke to a support consultant Rhyan and he promised his manager to call me, we now in May and no one called me yet, Yesterday morning i received an sms vuma is going maintenance from 4pm to 5pm in our area and we will be down an hour, we down from 4pm yesterday till today, when i call in to Afrihost they said its not maintenance there is an outage and we would of not known this if i did not call in, i run a business from home and every time the fibre is down we need to make alternative arrangements.When i informed Afrihost i want to cancel she inists we need to pay a cancellation fee that is utter nonsense as we receiving poor service from day 1 and all the times we down they billed me for usage they must take this money towards the cancellation, the lady insists we pay a cancellation and she states that no manager or CEO can waiver this cost, i am now taking this matter to my attorney and i will take this matter further, i will block Afrihost and remove their equipment, i want this link cancelled, the account cancelled and the debit order stopped, as for many months Afrihost promised a refund but till date nothing, pathetic service, absolutely no customer focus, lack of concern and money making service provider and to top it off they in creased our fees.
