Doesn’t surprise me at all. I signed up for an internet plan with a provider once, but they never let me login to pay the bills. After they started threatening me with collections and several phone calls layer it turned out they were billing someone in a completely different city. Complete shambles.

I have a comparable dispute with an old ISP from an old apartment. Their system had me as still receiving services there for many months after I cancelled and moved. Every year they send me a final warning saying it'll go to collections (the fact that it hasn't actually gone to collections more or less tells me I'm right, lol). Every year I'm grateful it's "just" an ISP and not the government because the government would've escalated the fine to a bajillion dollars and issued a bench warrant by now.
