New customer confused

I moved recently and was strong-armed into getting Xfinity since the vastly superior Verizon Fios was unavailable in my area. Since I had no other choice, on April 16th I created an account, built a plan, and scheduled an appointment for a service tech to come in on April 20th between 3PM-5PM. I have no indication that the service tech is coming, since when I log into the website, I keep getting logged out. When I click on manage appointments, the page says the service is down. How can an internet company have this insult of a website to their customers. I'm a pragmatic person, so I read the list of other ways to view my appointment. I try using the Xfinity app - after login it states that my Access is not Authorized; I have signed in successfully, but I must be an Xfinity user. The same happens when I call "support". How can I confirm if I'm an Xfinity user if both the website the app are giving me accessibility issues. A quick search shows this is an ongoing issue for customers for years. Am I able to speak to a real person, or is this just going to be my experience for the next few years until Verizon comes to my area.
