Promises not met after sale of car

I purchased my 2011 Corsa 1.4 sport at McCarthy Arcadia 21 August 2015...<br> <br> To my acknowledgement it came with no service book but was promised to get one asap since the car was collected at Witbank and brought to Pretoria.<br> The car has a problem with its Day Time Running Lights which don't turn on at the same time as they are supposed to.<br> <br> Further along while driving the car, the car spanner warning light came on and the car had loss of power. I reported this and the car was taken to GM Silverton and they said the car is fine<br> Told them that the car only has loss of power only when the spanner warning light turns on while I'm driving which I was told I should report the case again if the car experiences such again to further investigate<br> <br> Well on Sunday it happened, I contacted GM Silverton yesterday regarding the issue which I was told to bring the car in today but when I notify Solly from McCarthy Arcadia to go with me, he was rather rude and told me to go there myself because he's not available and stopped he's contact with me when I asked him who will be liable for the costs since I found the car at McCarthy Arcadia at the state it was in. Worst experience ever for my first car
