Exactly what I thought. Over the years I have done thousands of repairs and on the very rare occasion something could go wrong and make me look like a total tit.To be fair accidents do happen and at least he was fully insured and has apologised. Not sure how the wrong fixings were used, we don't know the whole story. You will soon know if he knows what hes doing ref motorised set up.
His other reviews are excellent.
Thankfully we normally learn from those times and it's just what makes us better at our jobs.
I had seen some of his reviews which is something I never did with the other firm. Slipping up in my dotage.
