Back when I lived in the northwest, something similar happened; I had Comcast for a year for phone and internet, didn't like it, and decided to switch back to Centurylink. During the Comcast install, I watched the guy physically break a part of the telephone network interface box. I just sorta assumed he was incompetent and fat fingered it, but the Centurylink guy who fixed it put some sort of weird plastic mold in place of the part that the Comcast guy broke. Ever since that happened, I've sorta half wondered whether that happens more often than not.
