Worst Service Ever

I have been taking my car to this dealership for its service for over six years. Only one service has been done at Honda Northcliff in all this time. Since the end of November to date I have taken my vehicle to the dealership for the same issue without resolution. The car switches off whilst driving, it's an auto. First they blamed the spark plugs, then it was a loose battery terminal, the latest is engine coils. Now they have given me a car that is making noises when I called to ask them they said that it was the shocks. They have quoted for shocks. Yet they were not fitted. Now the people who gave me my car will try pin the blame on someone who was on leave.
