Mac Office remove issues

Hi all
About 2 weeks back I removed Microsoft Office from my Mac. Or better, I tried to remove it. I started the remove program, which was actually showing that I had 2 different versions installed (which actually is not the case). So I checked both versions, but the uninstaller terminated immediatly with error code -50, unexpected error occurred...(Microsoft still seems not to be able giving clear error messsages to the user). So I restarted the uninstaller and guess what? The uninstaller told me I had 3 versions installed....Hmm, ok, again, I select all 3, and the uninstaller again breaks, same error.
So I tried to see how to remove it differently and saw the there mostly are only procedures, which need a lot of manual steps, so I thought, ok leave it on my mac. But after I restarted my Mac another day the Office was gone...Huh????
Well, I thought, ok, that's what I wanted anyway, but of course, not everything was deleted. Has anyone ever experienced a similar issue with removing Office?
Thanks, René
