The message says that this is Officer Jane Smith from the IRS. Don't disregard this message. Return our call before we take action against you. They close out the message with, "Take Care." I returned the call and spoke to "Michael" who was probably Abdul from Indonesia. He asked me for my phone number because "Jane" was unavailable. I gave him my phone number and he gave me a name that wasn't mine. He apologized and said they wouldn't call back. An hour later, they called back.
