reception don't have a clue what there lying to customers about that customers get frustrated.
Spot on edde, 9/10 service desk, service advisers whatever you want to call them don't have a flipping clue, they're trained on the job and spend more time invoicing(sp) warranty jobs, or filing job cards, rather than getting trained up properly, dealing with customers etc. Most have no mechanical knowledge, if your lucky they might be an ex-tech/mechanic, but imagine if you asked them why your depashers gone bang, or any serious technical question. Most of them just blag your way through it, one day at a time. Also, some customers just aren't bothered, so why take a mechanic off a job earning the boss £60 an hour, to tell 70/80 year old Mrs Jones that her tank sender was replaced because.... When you could have a service desk person ushering out them to get the next job in. Not saying its the right way but sadly how its done.
As said, as with all big companies, not just car dealerships, theres always some 'big boss' sat upstairs finding any way to reel the cash in, not the the grafters on the shop floor but for the bigwigs. How many good sparkies are about nowadays? As in spot on ones, same with builders/plasterers?? I'm not saying all techs are spot on, I'm sure more than half are completely useless, but its not always them.
Edit - to be honest I don't know why anyone goes to Renault other than for a stamp in the book, or if your minted. Theres far cheaper specialists that can do the same job, but half the price, Ie Yozza, Rentech etc
