This is a collection agency. Either you or someone you know, or knew has defaulted on a payment arrangement. Your number is tied to this record. Relaying the message does no good since now they know your number is a good number for a response. Just delete it.
**If you live in a Default Judgement county; check your own name with your county clerk's office. This is also a precursor to filing a suit against you. The court has no obligation to contact you. The plaintiff does. In a default county, the plaintiff petitions the clerk's office and they do it for you.

Known IRS scam. You can report the call to the IRS directly on IRS.GOV.
