Car breaks down after service... AGAIN

Car went in for a service and then broke down the next day. This is the SECOND time that the car has broken down the day after being serviced by Hyundai Bryanston. <br> Car broke down with my wife in it on her way to work, I work close to Hyundai so I drove over there to see how we could sort it out. Dealer principle was most unhelpful, suggested that I should phone roadside assistance and they would go and see what the problem was. He said he couldn't see how the service could cause a breakdown. He didn't even offer to make the call on my behalf! Fortunately the workshop manager overheard us and offered to drive out with me to have a look. Turns out the fuel filter was fitted incorrectly and he fixed in in 5 minutes, perhaps he can now explain to the dealer principle how a 'service' can in fact cause a breakdown. Still waiting for the dealer principle to phone and apologise for the HUGE inconvenience. Will never take my car back there as this is the SECOND time that the car has broken down after being serviced by Hyundai Bryanston
