Complaint Review: Janeth

Yesterday I offered my boyfriend's macbook in Craiglist, later that day some one texted me  telling me that they wanted to buy the computer, and it happened the same I have read about someone seems to be an old lady, in my case Mrs. Jacinta Whitehill, that wanted the computer to be sent to west Africa this is literally the text message: "I'm ok with your selling price, actually the item is a gift to my son who is in West Africa for his primary assignment with the World Health Organization (WHO), I will send you $1750.00 USD" then I asked this "Mrs. Whitehill" if I could call her and she said: "it would best if you call me, but I can't hear you will say through my phone the earpiece is not working that is why I text you"
Then they sent me 2 emails from Merchant Express (I will attach pictures). The Information seems legit, be aware.
I didn't send anything thanks to my boyfriend, he said it was really fishy since we started making the deal.
Thanks God we didn't send the computer, just be aware of these scams.
