Pretend to be IRS. Tell you all sorts of bad things will soon happen to you because you didn't cross the T or dot the I on your tax forms. But, if you send them money by Green dot money pak which are untraceable, the whole problem will simply go away. Total scam.
I received a message from this number on my cell phone. He identified himself as Office Derrek Foster. Threatening legal action and wishing me "Good luck" if I do not call the number or a response from my attorney immediately.
Left a threatening message on my home phone claiming he was with the IRS. Message was very unclear like they had a bad connection so I couldn't understand all of it.
