Aly, if you receive another call from this group of dirt bags try to extract as much information as possible.
Any and every bit you gain - even if it is totally bogus (e.g. current alias) - will be helpful.

Since receiving another harassing phone call from these A-holes at 10:15pm las night, I have made it my top priority to shut them down and see the principals prosecuted.

These people call for the owner all of the time. Explained that owner does not work here, and to stop calling. They say that the owner requested information. If the owner had then they would have the owner's cell phone number and e-mail address. We are on the business Do Not Call List. Told them I would report them if they kept calling. So let's see if it makes them cease the harrassing phone calls.
