Continues Network Problem

Yesterday, 12 Jan 2024, at around 20:00 I experience a network problem, meaning I had no internet, reference number ***2. Again today, 13 Jan 2024, around 20:00 same problem, no internet. What exactly is going on? I thought I'm paying for unlimited data, but it looks like there's a timer set or there's a limit that's been set for usage of data. If that's the case that means you are not the kind of service providers I'm looking for because I work remotely from home and I need the internet 24/7. If you can't provide me with the kind of service I'm looking for, then unfortunately this means I will have to look elsewhere for service satisfaction. When I try to log another ticket, it tells me I have a ticket pending and it will be resolved in 24 hours. If this is not sorted out, I will cancel this subscription because I'm running a business and I'm loosing a lot of money by not having internet access.
