571-431-1980 ... Caller ID showed ARM. Apparently a debt collector looking for a Mary McCartney who by the way does not live in our household. We've had our number for about 2 months. Apparently, she had this ph # before we did. I told the operator (after waiting for a person for about 1 minute) that she doesn't live in this household.
Scavenger debt collection agency, meaning they buy old and invalid debts and try aggressively to collect on them. Ignore them. They know they are not a legitimate agency.
