MegaExo Bottom Bracket Removal

The bearings on the MegaExo bottom bracket that came fitted to my CB are falling apart so its time for a new BB.

The problem I have is that I'm unable to remove the BB! I bought the correct tool ages ago in preparation for this day but I simply can't get them to shift. I started on the non-drive side and applied pressure in the opposite direction to the arrow and ended up damaging the teeth as I had to apply so much pressure. Before I damaged them all, rendering the tool useless, I stopped and thought I'd seek advice.

So any suggestions how to free up an seized MegaExo BB? I've applied GT85 but cant really see this doing very much.
