Constant connectivity issues and slow speeds

I signed up for a 10 up and 10 down fibre line with Afrihost (frogfoot) and have been experiencing incredibly slow internet speeds from roughly the second month. I've now had virtually no internet connectivity since Friday evening and am beginning to wonder what exactly it is that I'm paying for. Why the constant network/line issues? Why the painfully slow speed? The whole purpose of going with fibre in the first place was to have a stable, fast connection. At this point I'm considering returning to Telkom LTE which, while being intermittent (and possibly the worst customer service) was at least fast, for the most part.
