Great whilst it works, BEWARE THOUGH WHEN IT DOESN'T

I have been with mweb since April 2023. Have been happy with the product until Friday 22nd of September 2023. Since then the internet has been pathetically slow, ranging from 10b/s up to very briefly 1mb/s, or simply have no internet connection. On Monday 25th September I called the help desk about this. Spoke to one person who had me reboot the system on the router etc. So got hooked up again, and half an hour later the problem repeated itself. So I called back and spoke to another agent who then had me do the same things I had done a half hour earlier, and had me test speeds etc. She then suggested I put the TV on 5g and leave my other devices on the normal lte. This seemed to work initially. Then loadshedding hit and I went to bed. Last night, Tuesday we had sporadic internet. Tonight, there has been nothing. I called the help desk and after 15minutes waiting on the line, and remaining as second in the queue I hung up. How much airtime do they expect us to waste just waiting for them to answer the call? How much airtime must I waste just trying to get what I pay for every month? The sad thing is, I was really chuffed with my switch over to mweb until this happened.
