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 got a similar phone call, but from a 636-220-8698 number. The woman said she had an overnight package for me and needed to confirm my name and address and then also had my ex-husband's address. The package was supposedly coming from a P.O. Box in Chicago Illlinois.
