Can a repo agency contact your employer and slander your name?

yep

AKA, the Fair Debt Collection Practices Act, nope.

All a repo agency (or any other debt collector) can do is verify your employment and location. They CANNOT reveal ANY debt information (much less their intent to repo your vehicle) or even insinuate that you HAVE a debt. For more info on what a debt collector can and can't do, take a looksee at: http://www.ftc.gov/bcp/edu/pubs/consumer/credit/cre27.pdf If a repo agency DID slander you to your employer, please take the time to complain about them ... they have invaded your privacy and stomped on your rights!!
