Customer service and call centers

Spent three hours this morning with customer support and, apparently, other departments. The first agent was negotiating with me in good faith but our chat connection was disconnected. When it came back up again it was like starting from zero with a new agent who couldn't care less about me. That escalated to some "supervisor" who not only lied to me on a number of questions but was more than rude about the whole situation, constantly interrupting me and repeating things erroneously. He identified himself as Chyl, employee number EN (that's what he claimed) from the Philippines. Claimed he represented three different departments and couldn't transfer me to anyone else. Totally disgusting lack of service. Xfinity has truly fallen to the lowest possible levels. I plan to visit a store in person hoping to get better service. If I don't, I'll have to share my experience as far and wide as possible and switch to someone else. This was a horrible experience.
