Telkom zero technical support

Over the last month and a half i have had endless problems with Telkom and their lack of technical support. I have a 10m/s line with them and use mweb as my data provider. I have a premium account with mweb so that i dont have a soft cap on data. We use the internet for buisness as well as streaming all our entertainmetnt. After battling with them refusing to send a technician out because acccording to the them 1mb/s on a 10mb/s line is acceptable. They get arrogant employees to call me and tell me that they dont garuntee any speed so no matter what speed i get is deemed acceptable. He also tells me that because i have used 700gb this month i have got less priority than the 40 other people sharing my bandwidth on a contention ratio. I dont even use them as a isp so how can they limit me because of my usage when i pay mweb for a premium account.
