Terrible service- or lack thereof!

Terrible service from Vumatel! Afrihost is my provider, but Unfortunately Vumatel was the fibre provider. After installation I was getting SIGNIFICANTLY slower speeds that what I was paying for. I logged the complaint with Afrihost and was told Vumatel would get back to me with a way forward and a solution. 3 days later and I'd still heard nothing. I contacted Afrihost and they said that the issue had been closed by Vumatel as they stated it was not a fibre issue and instead was an internal issue- no informing me that this had happened, just closed it on their own accord without waiting for any response or update from Afrihost on the issue. HOURS on the line with Afrihost, loads of photos and videos later to PROVE that it is not an internal issue and VUMATEL is STILL claiming that it is not their issue. Currently I sit here still sending proof to Afrihost that this is an issue (they believe me, and themselves are fed up with Vumatel's service- or lack thereof). Even with all the proof of the issue, Vumatel is refusing to send out a technician to even just CHECK what the issue may be. FED UP!!!!
