BAD SERVICE NO CUSTOMER CARE

I took my car in due to a light displaying on the dashboard. I was told it was one specific problem which would cost R31 000. After the repair l took my car back and within two days the light was displaying again. After l took the car back l was told that the problem with the car was actually a completely different issue not picked up in the first instance of repair.The attitude l got from Mercedes-Benz M2 City was \don't care"attitude with no concern for what this all meant to me and the extra cost l was now being asked to incur.They had their R31 000 it was not an issue for them.The service l got from the branch of Mercedes-Benz was disappointing and l demand a proper apology especially from the branch manager who had a terrible attitude to my plight. I might not know much about cars but if a light goes on the dashboard people need to check all possible causes of this issue instead of picking one issue that turns out to be wrong.I am disappointed and feel that l paid R31 000 for bad service and bad attitude and worse of all l am now car-less with no hope of real remedy due to this bad service and bad diagnosis and repair.
