CONTACT POLICE IMMEDIATELY!!!!!!!! This is a 100% scam. They are claiming to be US Treasury. I have worked both for Collections and also with the Attorney General. The US Treasury does not call you, they do not tell you that you are going to be arrested when you ask them to remove the BUSINESS number they called, and they do not hang up when you asked for a number to be removed. I repeat Contact the authorities immediately!!!!!!

Got same phone call saying I was in big trouble!

They said they are the US treasury and I'm going to get arrested

No one is going to arrest you. This is a pervasive extortion scam well into its third year, bilking thousands out of millions. Hang up, block the number (if you have the capability) and report them to the appropriate entity:

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 OIGCounsel@oig.treas.gov 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:
