Ike

To be brief. Arrived in France last year to set up plant nursery. English builder did renovations. Because of bad work, we would not pay all of his very high bills. Got threatening calls and visits. Eventually partner and I beaten up by builder. Police came. Not interested, did nothing. He started to damage the house and stealing property. Told Police, still did nothing. Became impossible to leave house as we would find damage on our return. Eventually, Procureur made all four of us (builder and girlfriend, me and my, also male, partner - you decide if this is relevant) sign an attestation that all intimidation and violence would stop. It did not. Attacked again this week.Mail stolen so that phones cut off as we do not receive bills. Bank informed by him that we are going into liquidation so they pressurize us. Nobody does anything. Enlgish, so-called, friends, all back away - frightened or not bothered. French believe him - il est tres gentil etc. etc. And we, after all are, as he put it, only two paranoid poofs. What to do? Mayor keeps saying he will do something and doesn't. Police do nothing. Station often closed. Took them 45 mins. to get to us last time. Plenty of time to kill us! Suggestions please!
