Who called from 4155994435

I too keep getting the exact same message.  Now their is a name to the message. Officer, Nicky Johnson.  I do know this is a scam, however I can understand why people do call back.  I am in Sales so when I have time on my hands I am going to call back the number and waist their time and mess with them. Perhaps give them some bogus socials and credit card numbers. Let's see who is playing who.

Don't waste your time with them. All you will get is an earful of profanity for your efforts.

There are numerous telephone and email scams in which individuals claim to be employees of the Treasury Department. These scammers often state that they are from the “Department of Legal Affairs,” offer grant money in exchange for you wiring a small payment, or threaten to arrest you within a short period of time unless payment is made. Do not provide personal information or payment to these individuals.  Their actions are crimes under Titles 18 and 31 of the United States Code, and the Treasury Office of Inspector General is working to stop them.

If they claim to be from Treasury, report  it to [email protected] with a description.  If it was a phone contact, include:
the exact date and time that you received the call(s)
the phone number of the caller
the geographic location and time zone where you received the call
a description of the communication.

If they claim to be from the Internal Revenue Service (IRS) or it is about taxes, report it to the Treasury Inspector General for Tax Administration at:
