looks like the same old story. Spanish developers making it up as they go along, with little fear of being bought to rights. In the meantime the innocent victim, full of stress and bewilderment, spends a fortune and years, just trying to get back what is rightfully theirs.
Still seems that if you are a selfish greedy liar in Spain, then you will be fine. If you are an honest person just trying to get justice though, you have very little help from Spanish authorities.
We just have to keep plugging away though and believe it will change for the good, sooner or later?
