Poor Axxess Internet Bandwith/ Service on Top Tier Package. Why?

Since Aug/Sept 2025 their excellent service started to get really ****. I have been a happy customer since 2021, but now, even at the top tier 1k package, some nights I cannot even watch Netflix! I contacted their tech but its the usual up and down with no resolve. It seems the quest for subscribers and profitts have overtaken their usual excellent service and bandwith. Now I cannot even watch properly anymore. I downgraded to to the lowest package in Dec but the bandwith was so **** that I indicated I want to upgrade to the top package end of month. Strangely from then the bandwith was excellent untill I paid the nearly 1k on Thursday. Since the 1st of Feb everything changed to the ****ty bandwith again. I they luring customers to the top tier package and then its back to poor service?
