Maple Holistics

I purchased two essential oils from Maple Holistics and was offered a free sample product if I left a review online. I did so, sent proof and then was told that they were out of samples a couple weeks later. Ok, fine- but then they told me if I bought one more item they will send me TWO free products. So, they're able to send me two free products but can't send me one from the first purchase I made? I sent them an email about that and still haven't gotten a reply from them. No wonder they have so many good reviews, they promise free products for a review so people leave stellar reviews, and then they don't send the free products. Pretty shady way to do business.
