Booked car in. Told them what car and model when I booked it on on the phone. Arrived and it was clear they didn't have a clue or where to look for the aircon top up valve. I had to phone a dealer myself 3 times to help them. Told them exactly where the top up valve was but some so called aircon expert ignores this and starts taking parts off just to see if he could find it. Then it takes him 10 minutes struggling to put the part back on that had nothing to do with the aircron. When I asked why did he take that off I told you where the top up valve is and how to get to it, it hurt his poor little feelings. Instead of saying anything to me the customer. They took my car off the ramps parked it outside and no one had the courage to say sorry we are not going to do this now you've upset our delicate staff. Not once did I raise my voice swear or be impolite. It was simply that I asked what did you take that off for I told you where the aircon top up valve was. Apauling way to handle customers and if you couldn't do.it you should have said when I booked it in. Manager is obviously scarred of his own incompetent staff. Needs head office to investigate.
