Oh, you have my sympathy. I was in a similar situation one time, that was for weeks and weeks though. I lived in a building with three flats and two owners. The two owners hated each other - one would not pay the other, so he shut off the heating system, except in the flat HE lived in. The 78 year old lady and I were left with no heating at all! Nothing happened until I contacted the authoraties and they forced them to put it back on.

Did I mention it was a winter when we had up to minus 15 C.
