Debt collection scam. Received robocall from Brian Willinski, a "private investigator" with CAO & Associates. Caller is using spoofed numbers to make the call appear local. Recording claims there is a "pending claim" against me and references 855 number for callback. When I called, was threatened with arrest for "check fraud" and given a phony court date for my "case". Upon calling them out as a scam, they immediately hung up, although the robocalls continue. Scammer attempts to coerce people into "resolving" their "case" by making payments using a pre-paid debit card (which, of course, cannot be traced). Have reported to the FTC and Michigan Attorney General's Consumer Protection Division. Total SCAM!
