Worst Service and Quality of work ever

Worst service from Edendale Toyota,

I took my car in as it has a Nosie when the Electronic handbrake engages, vehicle has now been in there 3 times, and the last time they said the noise was fixed and warranty replaced the part, Yet the noise is still there and unchanged since the day i took it in , now i have to take it back and another day without a car, The foreman and the Service manager just gives excuse .

now they telling me they fixed it and over a space of few hours all a sudden the same exact noise occur from the other side of the car, How it this is true?????

now i must be without a car and waste another day of my time to take it back.

i logged a case with Toyota SA hoping they can assist me further
