    Make sure, 3 times, that you are turning it in the right direction.

    Then get an insanely large adjustable spanner (300mm or longer). Or if it's a one-piece BB tool, stick a big piece of pipe on the end to give yourself more leverage.

    I've had to quite literally stand on the spanner and bounce up and down in the past to loosen a BB.

    Depends on the BB and type of tool but I saw a great tip in a bike shop once. Use a quick release skewer to clamp your BB tool on the BB shell grooves if your BB is a hollow one. My BB tool kept slipping off the BB grooves but the skewer keeps it firmly in place.

    Of course I'll no longer have this problem because this bike has been nicked.

    That's a good tip actually. On square taper or similar designs, you can also use the crank bolt to keep the BB tool attached.
