Impossible to contact customer support

The most frustrating customer support experience I have ever had, I receive a notification from Xfinity that I have somehow used up yo 90% of my monthly data plan which is 1.2TB, virtually impossible as we're a 2-person household and never use up the limits of our data plan, hence I tried to contact support to get a daily breakdown of my internet usage. When I contacted support on the website, the live chat agent says he can't provide me the information about the daily data usage breakdown, hence I need to call the data usage escalation team on: 1-877-807-6581, I call the number and the robot insists on sending me a text link to a chat agent (I tried selecting multiple options and they kept sending me the support chat link) I spent over 10mins trying to navigate the robot to route me to a live agent, after an extremely frustrating loop, they route me to a tier 1 phone agent that again says she does not have access to the data usage breakdown and does not know why the chat agent told me to call this number. This is honestly the most frustrating [Edited: "Language"] loop for customers to navigate to try to get support, it almost seems that this is a tactic to deter customers from contacting support as you make it virtually impossible to actually access any sort of real support.

2hours spent on trying to contact support, no resolution given. No way to submit a written complaint on the website or send an email to the customer support department, it is unbelievable how extremely enraging it is to try to contact support at Xfinity, conversational AI and automation is supposed to help relief the customer experience, not to make it worse, but in Xfinity's case, their digital investments are simply ruining their customer experience.
