I ignored the call and let it go to voicemail. The first part of the message was cut off and the remainder was very hard to understand -- it was very staticky and muffled and the caller had a thick Middle Eastern or Jamaican accent -- but I did make out "...information about the case. It is very important that we hear back from you today. The call back number is 347.390.0685, I repeat, 347.390.0685. Thank you and have a great day."

2nd time receiving this call this person was hard to understand with a heavy accent, stated it was important for me to call them back today they have my address and the IRS will take action if I do not call them back today. I've paid my taxes so I know its a SCAM

A robo call, barely audible, caller had a Spanish accent, mumbled something about the IRS and that I must call them. Since the line was so static filled, hard to make out which number the caller wanted me call.

Called as a fake irs scam

I received exactly the same vM msg.
I've now added it to my list of BLOCKED numbers.
