"...We were promised tropical gardens a secure site and a luxury complex...."
Verbally, or is it written in the contract/memorias de calidades, and how specific is it? Who's definition of "secure" & "luxury" do you go by?
Sorry to sound pessimistic, but we also expected a "garden", but got a dump. After 2 years of trying with the developer, we finally took our gardener's advice to install (at great expense to the community) an automatic irrigation system, and low & behold, we now have a reasnoable (if not perfect) lawn. Unfortunately for us, this rather served to suggest that the developer had in fact provided a "garden", we had just failed to "maintain" it, which was obviously our responsibilty, not the developer's.
