Customer ******* @Renault Bethal

I own a renault clio IV 2013 model. Last Wednesday I noticed that my boot was stuck in the locked position and the front and back doors did not lock.I contacted the Renault branch in Bethal-Mpumalanga,they advised me to bring the car in so that they can check.About 15min or so,the technician told me that I will need to book the car in for a couple of hours because he tried re-programming the car without success.I booked it in for friday,6hrs later I called them to find out if they sorted out the issue.They told me that I needed to replace the computer box which will cost me R11 000.Puzzled at this figure and how minor the issue was I told them I don't want them to order the part and I will come fetch my car.The next day I travelled more than 90kms to a Renault centre in the East Rand-Boksburg.I didn't make an appointment but I was desperate because I couldn't fill up fuel,the petrol cap was also stuck in the locked position.The technician kindly took my car into the workshop and he came out 15min later with my car,all the doors could now lock and unlock.He didn't even want payment for his efforts.He said the issue was caused by a faulty fuse.Filled with relief and anger I ask myself why did the technician at the other workshop want to rip me off in that manner.Was there a proper diagnosis done on my car or not?I'm completely appalled by their service and incompetence.This goes to show that they ******* customers who don't ask questions and are not clued up about cars.I however applaud the gentleman who assisted me in Boksburg,I really admire his technical s****s.
