Internet down for almost a week now

We have been without internet now since last week Saturday. After numerous calls , emails to Vumatel and my ISP provider Afrihost, I doubt these call centre agents has a clue what's going on . No constructive communication and after several complain logs, no Vumatel technician made contact with me yet, even after I was promised twice they would ...here we stand on day 6 and no one made contact and still no internet....poor poor service. #payingcustomer
