Car giving multiple issues

I bought my car from Pretoria branch in October 2013(2012 model). Two months later,I noticed that the car shows mark of repairs inside the bonnet,The front bumper also started falling and paint peeling off.. I contacted dealer to inform them about the issues,, They took my car back and done some repairs however few months down the line, the front bumper is starting to peel off again. I raised this issue again but this time I also wanted to know what happened to the car initially.. I was asked to take it to panel beater of my choice for 2nd opinion which i did and the panel beaters confirmed that the car was repaired previously and was a poor workman standard.So I gave the same feedback to Daniel from Pharaoh and we agreed to meet panel beater so that they can show him all this faults.. He did not come.that was the last time i heard from him. <br> On 23 April 2015, the same car was diagnosed with prob-shaft problem and the specialist confirmed that someone has done repairs on the car previously and that parts used was on a very low standard.Nissan coted R5100 for repairs.<br> I am convinced the car was previously involved in an accident before I bought it.
