I received several of these about 4-5 years ago. Always a broken accent. I filed a complaint on each one - of course, never heard anything about the complaint - other than “thank you for......”.
I never could figure out what the scam was as it was just threats if you didn’t call them and police would be at your door but where was the scam? Maybe their training hadn’t taken them that far..
They would try to get you to pay by offering to settle for a small amount if you did an electronic bank draft. They would then drain your bank account.
