Several times they have called my office and asked to speak to the person in charge of the AT&T bill. I told them several times we do not have AT&T. Today they decided it would be "fun" (I'm assuming) to call my office several times in a row using different "goofy" voices then scream "Oh that's right! MEH!" and hangup when I inform them we DO NOT HAVE AT&T. They name shows up as anonymous, but it always the same number.
