Username is Not Valid Issue[Edited]

Linda,

I've been an Xfinity/Comcast customer for over 30 years. In all that time I've had the same email address that doubles as my user name on my Log In account. I use two Windows based computers to stream live TV. One in my home office and the other in my kitchen. I use both daily. 4 days ago I was asked on my Kitchen computer to log into my account with user name and password. No problem this happens periodically. I typed in my user name in the field and got a message saying this user name is not valid. I tried several time making sure to spell everything correctly - with no success. I tried calling tech support and had a [Edited: "Language"] of a time getting around that horrible automated machine assistant. Even after I was forced to wait for a remote reset procedure and all the other obvious equipment checks I knew were OK - It still did not recognize my user name. Finally after fighting with that awful AI assistant I got a live person. This tech support person told me there were issues with streaming services and they were going to get this resolved in a few hours and to try logging in again later. Even though I did not have any issues with my office computer and could access my email and live TV as normal. I felt like tech support was just trying politely to blow me off but I complied with the request and didn't attempt to log in until 24 hours later, the next day. Of course, I had the same issue. Xfinity/Comcast does not recognize my user name and I can't go any further. I tried to use the live Chat on the Xfinity website but it refused to let me Chat with a real person. I spent almost an hour going round and round with this [Edited: "Inflammatory"] Chat assistant with no resolution. Now I am frustrated and [Edited: "Language"]. I tried using my X account and contacted an Xfinity Agent via instant messaging. They wanted me to provide them with my full name and address to verify my account. The X platform is not secure and I was not going to give out any personal information and so once again I am not able to get any help with this problem. I am now reaching out to you on this forum to see what I can do to get my computer to recognize my user name. This is now Day 5. I pay $305.00 a month for the Xfinity/Comcast internet and TV service and this is what I get. Unfortunately, you have us by the short hairs as there is no real competition. AT&T is worse and Hughes Net is a joke. I've been waiting for Sonic to get to my neighborhood but that could take years. So I have no choice but to deal with your horrible customer service and hope I can get this issue resolved. Let's see if you can help me.
