Kia service center ****s.

We run a small business and rely on these cars for income. This hurts us more than you know. A few weeks ago one of our vehicles came in for a standard service. During the service, we received a notification from Netstar that the car's battery was disconnected. Upon collection of the vehicle, we queried this with Kia Stickland workshop who denied disconnecting the battery. We inspected the vehicle only to realize that they had also removed the timing chain from the car. (the car was booked in for regular service NOTHING MORE). I believe that the battery was swapped with an old battery and only God know what they did with our timing chain. This week we booked another car in for a fan-belt replacement. No one contacted us to confirm the cost or to request approval for the job. Around 17:00 the service consultant contacts us to inform us that the car is ready for collection and that the job will cost R2700. (madness). Why do we get informed at the end of the day that the car is ready? With no previous quote? With no approval for the work? We arranged to collect the car at 09:00 the next morning. Upon collection the service consultant is not present, we wait for about 45min while another consultant assists us. The other consultant informs us that the fan-belt replacement will only cost R1260, and not R2700 as per the previous consultant. While inspecting the vehicle we discover that the vehicle's rev-counter was not working, it was shuddering and had absolutely no power. The original consultant finally arrives at about 10:00, we inform her that we're not happy with the service, and are appalled with what's happening with our cars every time they come in for services. With an attitude, she tells us that she would have let us know when she was available to hand the car over. After specifically arranging with us to be there at 09:00. Before an argument erupted, based on our history with this shocking workshop, we decided to leave. I want to know why there is such a large disparity between the two amounts for the fan-belt?; I want to know why work is being done without authorization?; I want to know why other items of my vehicles are being tampered with while in for standard work/services?; I want to know why my timing chain was worked on without any notification?; I want to know why my battery was disconnected/removed/******/swapped?; I want to know why I was **** to about my battery being removed? Ladies and gentleman do not trust these corporate ****s. They will lie, cheat and ***** as far as possible to make target. The warranty your car has isn't worth the paper it is written on, and the service levels are worth even less. You can rest assured that I will be taking this further.
