appalling service and follow up

On Friday 23/10/2015 I asked my husband to take my chev aveo in because there was an oil leak that was supposedly fixed 3 months ago. Upon arrival, he was told that the car is not in a condition to be driven but they don't have a courtesy car for him so he can take a chance and drive it home and bring it on monday. On Monday he was served by Caroline. She called after 5pm and told him that the car is ready he must come and get it.When asked whether a driver is coming to pick him up, she said no the drivers have left, he should have made plans to get to where ever he needed to be, they'll only send a driver the next morning. So he was left stranded.We then e-mailed the dealer principal to let him know about our dissatisfaction only to be called back the following morning by the service manager. For our last service,we dealt with Caroline as well and never received an invoice for the work done.She kept promising but no action.Daniel Steyn was also e-mailed and never dealt with the matter.When we requested the documentation for the oil leak,Caroline said she will send it the following week but she'll probably forget so we must call to remind her.Disgustingly poor service. Never again
