As you live in the province of Puerto Plata then I would suggest that you go there as you are getting no help from the local Sindico. If my information is correct the senator for that
district is Francis Emilio Vargas Francisco (f.vargas@senado.gov.do ). For what it is worth a Senator can take any ideas presented to him by the populace and present it or them to the house as a law to be discussed and voted on.
As to your dealings with the Sindico I am interested in hearing if you have in fact attended the weekly meetings held at the Ayuntamiento as they are open to the general public. Also, whether anyone has presented this problem to the assembly and what their reaction was in front of the whole public that is or was in attendance.
