Who called from 2027549903

I received a call saying this is the final call advising me that the IRS is about to file a law suite against me and to call 202-754-9903.  I'm sure this was a fraudulent call.  If the IRS was going to file a law suite I'm sure I would have received a certified letter.  Additionally, there is no reason they would do so.

I also just received the same call advising me the IRS is filing a lawsuit against me and I need to call 202-754-9903.  Ditto Lori.
