Poor fault finding- Faulty lighting circuit- Pay or not?

[ipf]

Perhaps I'm being negative, but if he couldn't correct the new problems he caused while he was there it is unlikely he will be able to fix them at all.

I'll be positive and say I agree.

Along similar lines.
I got a call to investigate fault on lighting circuit (which sounded quite simple) and coincidentally I was in the area so said I’d have a look for £60 (too cheap I know but I was like 2 roads away), and really expected it to be a simple fix!
So attended, found/rectified fault within 15minutes and client paid me £60 then said - ‘The other electrician charged £100 was here over an hour and didn’t even fix it’!!!!
