These are debt collection agencies that are contacting you, and what they are doing is illegal.

So Savana, I hope you realize you are violating a federal law.

"Report any problems you have with a debt collector to your state Attorney General's office and the Federal Trade Commission. Many states have their own debt collection laws, and your Attorney General's office can help you determine your rights.

The FTC works for the consumer to prevent fraudulent, deceptive and unfair business practices in the marketplace and to provide information to help consumers spot, stop, and avoid them. To file a complaint or to get free information on consumer issues, visit ftc.gov or call toll-free, 1-877-FTC-HELP (1-877-382-4357); TTY: 1-866-653-4261. The FTC enters Internet, telemarketing, identity theft, and other fraud-related complaints into Consumer Sentinel, a secure online database available to hundreds of civil and criminal law enforcement agencies in the U.S. and abroad."

Contact an attorney in your area and see if there is grounds for a harassment suit.

I just received this call and the caller identified herself as a representative from Overnight Express asking for my husband.  She said that she had a package that would be delivered in 24 hours.  When I asked who it was from, she said PO BO 288, Chicago IL.  We have not ordered anything and I will wait to see if in fact a "package" arrives.

Its not illegal if you are not collecting a debt.

IT IS STARTING AGAIN!  NOW THE NUMBER IS 636-220-7205  WATCH OUT!!!

This call came in on my cell phone 636-220-7376.  I didn't answer and no message.  It appears from deeper research to be from a company called Players National Locator http://www.playersnational.com/index.asp .  They appear to be a skip tracing company based in or near St Louis MO, with a specialty in mortages and foreclosures, and foreclosure deficiency recovery.  It makes sense in my case, as I am struggling to sell a house prior to it being foreclosed on.  Best of luck to anyone in the same boat.
