Unfortunately, this GP is the only one in the practice who deals with a certain check up. Which I require. Have complained about how they wrongly diagnosed me with something previously. Pretty sure they'd be ok though for the checkup in the area they specialise in though.
AIBU to go back to them though, it may be awkward. Really though it's me who should be cross rather than them at me for making the complaint. I ended up in hospital because of it. Sorry this is all a bit ambiguous.
