Slow internet, consistantly for 2 weeks. No Resolution. TOTAL FRUSTRATION!

Slow internet for 2 weeks, endless errors, sms's coming through in the morning that they are aware of the issue, saying its resolved at night, and saying that you must reboot the router... 2 days later same issues... Between 5pm-9pm, there is just NO INTERNET!!! EVERY DAY! Already reduced subscription to 60mb as it could never get up to 100, and now every day I am sitting between 1.8mb/s and "maybe" 10mb/s... Asking for assistance from their AI, or sending a support email is just ignored... Absolutely a waste of money. Since I am only getting 3% speeds, can I also only pay 3% fees???
