Customer service is atrocious and service is inconsistent

In May, I requested a downgrade due to affordability however it had instead upgraded the service, internet speed is terrible and I have billing issues and since then to this day I have have been trying to resolve these issues. Instead I wait an hour to speak to a live agent and then continuously get transferred from one agent to another until they don’t respond and the chat has ended and I need to start a new one. The customer service is absolutely atrocious.
