Worst service from Kia Tableview

I recently took my Kia Sorento in for a 200,000km service and asked them to check several problems, one being the lights which is also listed on the service checklist, so I shouldn't even have to ask. One bulb was fused, yet when I received the car back it was listed on the invoice 'checked all lights' but was obviously never done as the one bulb was still fused. This makes me wonder what else was ticked off as checked but was never done??? I was also charged for 9 litres of oil (Total Quartz 15w40) at 164.50 per litre, a total of R1480.50!! This sells at Makro for R239 per 5l!!! How is this even possible??? There are several other problems that I asked them to check, which after an entire day they were unable to repair and told me I'll have to bring the car in again. The follow-up call from the company used get client feedback was pointless as I complained about all of the above and was assured that the service manager would call me back, which has not happened. This is the worst service I have ever received from a motor dealer (Kia Tableview). Their service has grown progressively worse over the last few years, which is very disappointing. It will take one helluva lot to make me look at Kia again as a possible future purchase.
