Renault -Disgusting Service

Is there anyone else out there that will not buy another Renault due to the lack of diligence and customer service and care? From Imperial sales to annual services, I am appalled at the calibre of commitment! What training does Renault use to train their staff or should I say they obviously don't! Absolutely nobody takes ownership of delivery of whatever service they are supposed to......we bought 2 Renaults in our family at the same time and our experiences with Imperial Stellenbosch & Durban Road - Bellville and then the service centre in Stikland has been disgusting. My 2 year old Renault went in for it's annual service a week ago and I still have no idea when I am going to get it back as absolutely nobody that can make decisions is available to be spoken to and they do not return calls either......no courtesy vehicle has been organised, though promised etc.........the list is very long as to my dissatisfaction......it's a shame because I like the vehicle but can't wait to get back to Ford or Hyundai.
