Robocall credit card interest rate scammer.  No identification as to what company is calling, what credit card they're calling about, and no option to opt out of future calls.  Mentions a letter I "may have received", but again, no company information.  I looked up this number, and it's associated with a company called Archie Andros & Company, which is an unclassified business services company in Milwaukee, WI, that was administratively dissolved by Wisconsin Secretary of State in 2013.  The phone number was probably spoofed.  https://www.consumer.ftc.gov/articles/0131-cr ... reduction-scams.
