I've gotten numerous calls from this number. (Sounds like a recording) it's a lady calling for an Attorneys office "Heather Gray" saying that I owe money to the IRS and I need to contact this office right now as this case is time sensitive. It's a SCAM! I owe nothing to the IRS and if I did the IRS said they would only contact by mail. They do not call! My caller I.D says call is from Anaheim, Callifornia. I just received the same call from another number (818) 330-5440 La Crescenta, CA.
I too just got a call from 657-549-5778 from a Special Agent "Heather Gray". It sounded like it was a computer talking not a real live person leaving the message. I do not owe the IRS any money. This is a total SCAM.
