LPA - not honoring contract on what was sold to a customer

What I was sold and what I got - two different stories. I was sold a RED week contract at a specific resort, for a specific week. My dates keep on changing and my time share for this year is on a WHITE week - not what I paid for. They keep on referring to the module M1 - why did they not book my week 15 years in advance at the resort after I signed up? I have asked for historical data reflecting how many times I was booked during a RED week as per my contract and to date still no response on the data required. What you are sold are not what you get. Be very careful. Not happy at all.
