Unreliable Vehicle Service Centre

Took my Citi Golf to be serviced at KOOPS Gezina, being impressed by the replacement of a water pump on the vehicle. Afterwards, a complete different scenerio - the breather pipe was damaged by the mechanic, the clutch on the vehicle is still malfunctioning, after replacing wheel bearings a wheel balancing was not performed which caused the front brand new tyres to be worn out, the engine is giving issues of slugging (no power), wiper pivot shafts was not replaced as requested after spending more than R10,000.00 on repairs. Requesting repairs are met with - it's not necessary. My vehicle is in a state which is going to cost thousands in repairs due to incompetence by a mechanic. It's us as consumer's right to complain about such incompetence. This matter will be referred to the AA as well RMI/MIWA which they are registered with.
