Get 2mbps instead of the 20mbps I’m charged. Nothing being done about it.

Hi my name is Gcina, I live in Cedar Acres Estate and we just got Vodacom Fiber in our complex. It was fine last month when we had just fitted it, but this month I’m getting 2mbps compared to the 20mbps I’m paying R800+ for. It’s so bad, I can’t even send emails, and I’m a freelancer working from home. They aren’t doing anything about it. I called and they say they are on but I’m sitting here paying extra using cellphone data. Please help, no one at vodacom is doing anything about it. My reference is SR171 ********** 06
