Poor and unprofessional service

Mechanic could not fit rear wheel bearings properly.Workmanship was so shoddy that the Vehicle wheel bearing gives in after 20 km of driving.Owner refuses redo the faulty bearing.He does not belong or associated with any vehicle regulator.He obviously does not follow a code of conduct.Pathetic mechanic.I had to take the Vehicle a number of times to him for the same problem but did not loose my temper.Owner was rude and arrogant despite his poor workmanship and failures.
