French Neighbours

I got home about 30 minutes ago, and found an envelope taped to my door, with "EN URGENT" handwritten on it. I opened it up and saw a letter:

Je suis Fabienne Xxx, votre voisine "en dessous". Ce matin at 6h30, j'ai trouve une fuite au dessous de l'evier. Le symdec est prevenu et le plombier m'a signale que la fuite, en partie, venait de chez vous. Auriez-vous l'amabilite de me telephoner au 01xx62xx34 pour prevoir une visite du plombier et eviter que les degats ne persistent. D'avance, je vous en remercie.

Had to get Google to translate it for me (after I deciphered some of the words because the penmanship is just horrible):

I'm Fabienne Xxx, your neighbor "below". This morning at 6:30 am, I found a leak below the sink. The [symdec] is accused and the plumber has said that the leak, in part, came from your place. Would you please call me at 01xx62xx34 to predict a visit by the plumber and avoid the damage that can persist. Thank you in advance."

I left her a message on the answering machine and left my number, and on Monday I'll get the rental service people to handle it.
