the message said to contact the IRS so I won't be arrested....  which made me curious if this was a scam since I can't find any reason I would be arrested....

Received a call they left a message , didn't call back

I called the number back being from our home town the gentle that answered the phone said he was an officer. So I asked for his supervisor then a gentlemen came on and said he was from the IRS lots of noise in the back ground and both were foreigners that I did speak too. So I proceeded to tell them I was calling JAG about the phone call after I called hom every name in the book then he hung up on me.
