I am very sorry to hear you are experiencing issues with the service.
Unfortunately I have been unable to locate your account via the community details to check things from our side but if you could access your Hubs advanced settings and post your network logs, we would be happy to take a look. Information on how to do this can be found here.
You can also run a BQM (Broadband quality monitor) and share your link to this thread 🙂
