Extremely bad service

<p>I booked an annual service at kia menlyn and told the service consultant that the car idles uneven. I asked if they would let me know what the fault is before they do any work beyond my service plan. They phoned me to collect my car. As I arrived(took leave at work)I had to wait for the job card to be produced etc. They informed me that the water pressure was low and that they could not wash or... vacuum my car(other cars to be sold was being washed). The lady also then gave me an invoice of R800 saying the spark plug was wet and they had to dry it...the mechanic booked a hour for just doing that. The car is still idling uneven and now have to pay again for the same thing. Kia Menlyn in unprofessional and their work ethic is questionable. This was the second time I had poor service, dont take your car there even if it seems to be a good area to take it.</p>
