Greater legal protection for buyers of Spanish property

Dear Sirs; I have bought a property in Barcelona, in May 2014 with the purpose of achieving a retirement income. After refurbishing the property, and placing it in te market, it was found to be unfit for living due to flooding and humidity issues. As a result I filed a court case in November 2014 requesting the annulment of the sale, which I partially won, because the defects were recognized, and the court mandated that the sale be reverted, but did not recognize me legal costs or costs such as utility, refurbishment & administration. I am now in the process of trying to recover the money, but the process is continuously stalled by the court (jurisdiction being the village where the sellers live), and so far all that I have being granted is the ability to recover 182 EUR/month which is obviously less than any interest on the money (and without interests it would take 36 years to recover the money). Do you have any suggestion of an ombudsman or how to make public this case? Best Reg
