Initial call was to my wife from a blocked number. Stated attempts to deliver legal documents were unsuccessful, provided 2 valid mailing addresses, asked for contact information for me. Would not say what this was regarding, except that it was on behalf of an employment agency. Second and third attempts were to me directly by phone, claiming that they were a company that collects debts. Emailed a "settlement offer" for a non-existent debt that is supposedly from US bank, need my credit card information and payment within 4 days. Fake debt was for over $3,100 and settlement offer was for just over $2,100.
