I just got a call from the number while on another call, so I rejected it. I figured it was Diamond Resorts, thank you for confirming, Laurie. Here's another number they've been using:

I am getting very annoyed with this. Which is unfortunate, because I loved both of my stays at Mystic Dunes in Orlando. Diamond Resorts owns it. I emailed them yesterday and told them to take me off of their list. And politely told them that if they didn't, that I would be making a complaint with Mystic Dunes; leaving a one star review on websites; and would not stay there again.
I'm not going to take much more of this from them, but I'm going to give them a chance to respond before taking action.
