Bad service

To cut a long story short.In September 2018 i serviced my at at SAC Centurion.Normally i do not check my oil and water level because i never had a problem with that .Yesterday at Sasol i decided to check the oil and water .To my surprise i was told by the petrol attendant that my oil level is tooo high.I got of the vehicle and did the test 3 times and it was vert high. I have been driving for about 6 months to Midrand and back.Luckily nothing happened to my engine.I took my car to a service center close by(05/03/2019) and got the oil drianed to the correct level.I tried calling them several times no one answered. No more will i be taking my car to SAC Centurion.They nearly cost me my car.
