Can't access the screw on the soap dish with a drill. Could just hacksaw the case to bits I guess; it's dead anyway.
The towel holder actually spins on a central axis, it's as if the screw is doing nothing. Have you got any other photos of the bracket? I can't tell how it works.
There's three of these: the cup / TB holder, towel holder and soap holder and the screw on all of them turns but does not release. How is that possible?!
Unscrew the grub screw completely, it might still be holding the bracket even though you have unscrewed it a bit. There's not much to it, if that grub screw comes out then you should be able to remove the accessory before removing the plate behind.
