Poor to zero service

Mweb is currently charging me for a 100mbps / 50mbps package with annual increases. However, I do not receive that internet speed. I have been querying this for over year and the billing there of. Most recently I have to spend hours and loads of airtime just to speak to someone with no joy. I have emailed numerous times only to have it fall on dead ears. Only for an agent to confirm the support email is unmanned. I have used all their platforms WhatsApp, online, live chat. No one responds. I am being ****** monthly. Their systems do not update accordingly, so it's pointless checking billing, never updated. Sitting without a connection because is there is absolute no level of decent service, no service actually. And how convenient that all their office are remote, they are getting away with ******.
