Failed Breaks,Failed Services

Took my car for service at Renault Paarden Island on 29/05/2019, i got a call advising the car needed wheel alignment, and I declined. On my way from the heard a strange sound when I apply brakes and had to apply a firm press couple of times before it worked. I called the service center on Monday 03/06/2019 to advise them of this. I was told my call will be attended too all 3 times I called that day. Called again the next day and was told the same thing, only last week I eventually got hold of the sales consultant Mr Richard(Richie) as he answered at reception. I told him my query and concerns as to why they did not advise me the brakes needed to be replaced. I live in Kraaifontein and the N1 is a hazard. He said he'll get back to me and till my husband called Monday and again no avail. I went to the service center yesterday and still he had done no research on my query and told the manager about my query. I asked to speak to my manager Muneeb Petersen he told Richie he can't see me at time and did not even say I could wait for awhile as his busy. This is very unprofessional. He send a message via Richie I need to make a appointment for Tuesday. I'm disgusted in this manager who sends messages via the employees they can't face /treat their clients with respect and dignity. The lack of service at Renault Paarden Island will endanger your life! Why is the mission statement broadly posted on the walls to entertain the clients and they can't deliver??
