2003 Mercedes Benz E500 SBC Sensotronic Hydraulic Brake Unit

An independent mechanic changed my two front rotors, pads, sensors and right passenger side wheel bearing. Afterwards, the SBC system was completely malfunctioning; Brake, ABS, SBC messages. When I first start cart and apply brakes, a noticeable binding and gripping of wheel bearing front repair occurs. Toof to MBZ dealer for Star diagnosis and they indicated the repair job was shoddy, separation issue with bearing. SBC unit needed replacing, etc. The indy mechanic did NOT deactivate the SBC system, nor bleed brakes, and resurfaced the rotors. It took three days working on car to even get it driveable. No diagnostic system used except a little handheld device that he used. He even took car to "buddy" shop across street to try and turn off messages. Unsuccessful. My question is did the indy mechanic's negligence cause the dysfunction and problem of the SBC system? What can be done to rectify the poor repair?
