Lifestyle Holidays Vacation Club [LHVC] review: Breach of contract

We bought a vacation plan and the only reason we bought it was because we travel to Cancun
Now they dont have the Cancun Properties isn't this a breach of Contract?
I am now refusing to pay anymore
All emails come back returned makes no sense
I have no desire to go to the DR!
Any help anyone can give me me would be appreciated
