Ready to quit Vumatel

I'm new under Vumatel but I'm ready to cancel because for the past few days I've tried to call in to get assistance with setting up my internet and you'd swear I'm not the customer but rather the ISP. There has been a pro rata of R650 for a 50mbps line but what are we pro rataring if I'm not connected.Could this be the reason Vumatel has been having connection issues. https://mybroadband.co.za/news/fibre/485041-secret-bonuses-and-fines-on-vumatels-network.html
