Hello, Yes, after all youv"e done it appears as if no one wants to take the initiative to put an end to the disturbance of which you are a victim.
You wrote that you filed a criminal complaint (porter plainte). Normally, you should receive a letter informing you of the statuts of your complaint (whether or not the complaint is being investigated of if the complaint was at a dead end and clasified (in French: "classée sans suite"). You can always contact the PARQUET (of the Procureur de la République) of your district to see if the investigation is going on or not. If your complaint was classified, then the only thing that you can do is file a criminal complaint before the French prosecuting judge (porter plainte avec constitution de partie civile devant le Doyen des juges d'instruction). You will have to pay a refundable deposit and after the payment of this deposit, the French juge d'instruction will have to investigate the case and determine if there is enough elements/evidence to make a conviction or not. This can take some time.
If there is enough evidence to make a conviction, the prosecuting judge (juge d'instruction) will render a court order ordering the defendant to be sent before the local Criminal court to be judged.
