Worst Service ever Experienced

Last year August I purchased a brand new Hyundai Grand i10. Unfortunately it had a rattle so i took it to Multifranchise Nelspruit just to have it checked out. They could not find the problem and my brand new car had a scratch. However as these things happen I was not too upset as Marlise the service manager assured me that they would fix it and she would attend to the matter as soon as possible. After a week I had not herd anything from her and after another week passed I decided to phone her. With a lot of nagging I finally took my vehicle in. There was another scratch that was quite deep - not there doing - which one could clearly see cant be fixed with just a buff. They idiot who repaired the other scratch then decided to buff that scratch. He buffed the paint right off and there is a white powder stuck in the door handle. So on the 2nd of November I contacted Marlise and asked when can they fix it. She said the first week in December as they would only have a courtesy car available for me then. So the week before December I had not herd from them. I went there and she said there is no courtesy car. It is January and still no progress had been made. Three months later!
