Claims to be IRS and has info on me but wants to "give me a 7000.00 Grant"

I also received a call from this number. Saying that I can receive an IRS grant for $7000. Asking me to call another number 360-515-7842 to speak to a Stephen Jackson. I waited a few minutes and they called back that if I wasn't interested that they could cancel that check for me. Something along those lines.  So I decided to call and just see what it was about. A letter was supposed to be sent out to me but there had been trouble with that in our zip code. That this check could be electronically deposited into my account. If I was not comfortable with that, I could go to a western union/ (some other name can't remember) and get my check that way  I would have to do a check for $299 that would be refunded to me within the hour so on so forth. You get the picture. Of course I told him I was not interested and said goodbye.
