It really does suck to have to use a real name at work. It really does suck. Most companies allow bill collectors to use an alias, for protection. Really, it makes more sense. You can review tax-assessor information in my local town and pick up addresses, reverse address for numbers, send mail, w/e you want! Kind of scary!
Lots of things you could do with bill collectors, just hard to think of the ideas. A third party collection agency is the best, they are more free to say as they please.
