Reduced internet line speed by Afrihost

I got a 1000mbps fiber line with Vumatel and Afrihost as service provider. For months I complained about reduced line speeds. I think I spoke to 20 different consultants at Afrihost via the Whatsapp help line. Each and every time I am being asked the SAME questions over and over again. I insisted to have a technician visit my premises and sort this out but guess what? On the day the technician came, the line speed went up miraculously to 1000mbps! This without him doing NOTHING and confirming that my setup was fine. He even stated that I am being throttled. For the next couple of days my line speed was fine until 3 days ago. My line speed dropped from 1000mbps to below 100mbps. Again I complained about this on Afrihost's useless Whatsapp line and AGAIN I was asked the same lame questions. I stated to the consultant that he must have a look at my previous issues and that my setup was fine but STILL he insisted that I take screenshots of speed tests etc. I even phoned the customer care line (again). I was asked to send screenshots of my line speed....NOTHING HAPPENED OF THIS EITHER. The irony is that I am getting 100mbps and paying for a 1000mbps.....I will surely be looking out for a more trustworthy and honest service provider! For anyone who needs information about this complain can contact Wynand on ***.
