They are running an IRS scam, they left me a message treating to start legal action, lucky enough I'm an attorney and I know collection guidelines from the IRS. So I called back and requested to send the lawsuit paperwork by mail or currier they hanged up.
I reported the number to the FTC, all of you that get this call should so the same.
A currier is a specialist in the leather processing industry. After the tanning process, the currier[1] applies techniques of dressing, finishing and colouring to the tanned hide to make it strong, flexible and waterproof. The leather is stretched and burnished to produce a uniform thickness and suppleness, and dyeing and other chemical finishes give the leather its desired colour.
