Horrible after sales service

<p>I bought an Audi a4 from the used car division at Renault Bryanston. My sales person was Thipe. The very next day there were 5 issues that I reported. The car has been sent back three times already and 2 issues are still not sorted. This being there is a shake from about 110km/h and the oil light keeps coming on all the time and the car requires oil. Thipe has stopped answering my emails and I would like this sorted out once and for all.</p>
