VUMATEL ZEROES

Vumatel installed a fibre connection to my house two weeks ago but although it was activated 9 days ago they have been unable to provide a stable connection. Their technicians appear totally unable to work out what is the problem. If they are not blaming the ISP (Afrihost) the best they can offer is to tell me to reboot the CPE which obviously doesn't resolve the problem. Unfortunately Vumatel are the only fibre network in my street and I have had to use them despite poor reports about their service. Unhappily for me it means no fibre until another network decides to come into my street.
