Caller from "Prince Parker," http://princeparker.com/contacts/, the collection agency of choice for AT&T. They have a terrible reputation, that was reinforced by the rude message their agent left on our business answering machine. What's more, this is more miscommunication and screwiness from AT&T, which kept creating new bills for us even though we closed our account months ago, and finally supposedly zeroed out our "balance" last Friday. Now it's Monday and their collectors are calling. Just ridiculous!
