Do you have problems with ALL numbers, or just the important ones?

Jessica Lopez called my deceased father's home phone wanting to speak with someone in regards to the "estate" and she was from the Office of Financial Crimes / Fraud Unit.  She gave a number to contact and stated that someone needed to call before they proceeded with prosecution!  I called the number back and gave her my home and cell (didn't know about this being a fraud!!).  I decided to call back around midnight from my cell and got a fast busy signal then I got a message that the mailbox was not valid....I called from my home and got the same messages.  I'm having problems with my dad's longtime girlfriend so I assumed this was some complaint she filed!  Wish I had looked it up before I called back!!

I actually left a message on her voicemail with my name and numbers. Have not spoken to her yet.  My husband is law enforcement so this should be fun!!
