Pathetic Service and Rude Foreman

Trusted Bruma Nissan with my X-trail's service for a number of years, but I think them taking on too many brands now resulted in slippy service. On my last service their none of the specific repairs I asked for, especially the rear window washer, weren't attended to, and on top of it the board under the engine came loose while I drove in the highway. The idiot of a foreman then had the audacity to blame it on my driving style, which I found out this weekend was actually the result of them never having replaced the clips needed, when it came off again this again while away, due to a pathetic repair job of just attaching it with thin cable ties, which have all cut through the board, destroying it. I now want a new engine floorboard from Bruma Nissan AND the idiot foreman to apologise in person.
