One of us is confused. RCI is an exchange company. You CAN'T buy into RCI. You must buy an underlying resort week, then JOIN RCI, for which there is a (roughly) $90/yr membership fee. Then you can deposit your week into RCI and go somewhere else (for another fee).
I'm thinking you just bought a timeshare. If you know no more than you indicate, and you 'just bought' at a sales presentation, you have the right to cancel (rescind) the sale. You should do that then come back to TUG and learn so that you can be an informed user and know what you are getting in for. Buying without knowing can be a very expensive mistake.
Let's talk?
