Get around there with a camera, whip up a dairy of the antics and get this bastid banned from letting property! You've gotta be in line for some kind of compensation!
Oh noes! Thats rubbish. Our radiators don't work but we gave up trying to figure it out - they spent last summer not wanting to turn off, so they were at full heat in the middle of the sweltering weather. Now it's fucking freezing and I'm wearing two pairs of socks because it's so cold in the flat.
