Live chat not working.

I was looking at my billing on my iPhone 16 app. I noticed that my bill was different from what it was before. I could chat with an agent briefly, but then the chat disconnected. Anytime I attempted to restart the chat, it started to loop to a screen where it asked me to log in or chat with an agent. I switched to my computer but I'm getting the same screen. I am also getting stuck in a log-in loop on my phone app now. I tried deleting the app, but the loop continues.
