They probably don't even know where or who they are calling ! They never say on their voice msg, the name of the person they claim is being sued by the IRS.
Now don't we know that the IRS would know & identify the person, by name, that they want to call them back? Definitely not the IRS! Scam!
Received a phone call on my mobile from 347-571-5992 with a recorded message saying the IRS has been trying to get a hold of me and now they are going to file a lawsuit against me. The recording said I needed to call 512-489-9160 to discuss the matter. TOTAL SCAM!
