BMW Clearwater appalling service ever

The worst bmw dealership ever , we trusted them with the repairs of the vehicle but instead they sucked money out of us for absolutely nothing. We bought new air shocks for the X5 and only took the car to BMW clearwater for computer leveling and they charged R1000 for that and we were told the car is ready for collection and drove 3 kms the car did the same thing there was a light on the dashboard and the leveling was still off. We rebooked for the car again and they now told us that the airshocks needs replacing cos the ones that we bought are fake and they charged R28000 and they called saying the car is ready for collection and we went and collected the car after driving the car the message on the dashboard comes up again and the leveling is still off and they said we should bring it back but this time around they said the issue is the front wheel level sensor which they charged R2000 and they said the car is ready for collection. After driving the car out of the dealership the the message on the dashboard comes up again only to find out when one of the technicians checked the car they found that the issue was a broken wire so all this costs was unnecessary 😢 and they refuse to refund.
