Mweb worst isp in South Africa

Should not even receive a -5 star for the last 3 months I’ve been paying for a 50/50 line but it’s never gone higher then 10/10. They say it’s Vuma but I’ve had their tech out here numerous times and the line coming in is 300/300 so it’s Mweb that’s at fault terrible service and company never do business with them.
