I had a few unsuccessful back and forths with different Fi agents about an issue, and after a couple of weird remarks, I developed the theory that first level agents get their performance scores penalized every time they escalate an issue. I would have them go through the same script over and over for over an hour, and even sometimes admit that I had an issue, but refuse to press that button. I have no hard evidence, but that was my read from the conversations, and would explain the bad support experience overall.
