From one of the best to one of the worst

Used to be very reliable and excellent to work with, but since late last year (2022) it seems to of been taking a big downward trend, in the past I never had any form of connection issues, now it is constant from my line being throttled when it's an uncapped and unshaped line to internet dying at the most inconvenient times, I work shifts from home so being down for 3 hours because there is no such thing as after hour support to assist with issues is a big issue, not to mention when you log a call for assistance you only get assisted 3 days afterwards with a call asking if the issue was resolved, yes it was but clearly not permanently as a couple of days later I sit with the exact same issue.
