Diamond Resorts review: presentation at mystic dunes fl

I went on a diamond resort presentation. They try to bully you.. A 90 minute presentation takes 3 hrs. I got up to walk out and the presenter threatened to not give me my 100$ for going. So when she sat me in the room with other people I stood up and said I have been here 2.5 hrs and am done. She demanded I sit down or go back in her office. She wanted to being me back to her office and I said no thank you all because I would not sit and I said I would like to stand. She threatened again about the gift so I said keep it and the manager walked over gave it to me and said I can leave. Crazy
