Scared driver

In 2014 I bought a Renault Clio 4 from Renault Princess crossing. Since I have been driving my car I had problems with the brakes of my car. In 2016 my car was booked in at Renault Princess Crossing for over a month to fix the brakes. When I got my car back the following was showing on the message lines: abs brakes faulty, no hill start assistance, check service, no brakes. The brakes on my car was not in working order. And ever since that I still took my car back for all the other services. On 1 August 2018 I took my car back for the 90 000 km service and explain the following: 1 The service lights are still on even after the major service, 2 The brakes are still making a fluttering and knocking sound when I tramp the brakes and after the service there is even an oozing sound with the fluttering and knocking of the brakes. Today is 7 August 2018 and my car is a danger to drive. Every time I get the same response all is ok with the car.
