Request for assistance to get original documents for my paid up car from Mecedez Benz

I bought my beautiful CLA200 in August 2019, assisted by a well trained a sales person who treated me so well. His name is Victor Maluleka at Melyn in Pretoria. I must commend his excellent interpersonal relations and marketing skills as this was the first car to be bought which had just arrived in the dealership. I was also assisted by a well skilled Financial manger Ms Hanlie Potgieter. Based these two employees mentioned above I would literally go back and buy another Mecedez Benz should the need arise. I applauded how they represent the values of Mecedez Benz SA. I however, in November decided to settle the debt for my car. This was done on 16 Nov 2019. ms Potgieter then committed to applying for the original documents on my behalf. Unfortunately the process was a bit delayed due to Dec holidays which I understood. Then the Lockdown happened and I could not make any follow up on my documents. After lockdown I started calling to find out but with no response. In August this year I took my car for the first service and it’s during this time that I was introduced to the new Finance manager as I was told that Ms Potgieter has left the dealership. Her name is Christelle. In her office she looked for my papers and could not find them. She then called Ms Potgieter how indicated that she indeed have received the papered and they are in the Office. ms Christelle further called someone within the dealership to. Heck for them in vain. I then requested her to re-apply for my car papers. Several calls and messages were left and up to now my original documents are still not with me. I called her last week and her response was appalling, she told me that I must remember that she was not there when I made the final payment and she therefore not responsible or obliged to assist me. She is not responsible for what happened before she came. I made her aware that this is not about her but it’s about the dealership and that she is the fad of Mecedez Benz. She later said I can proceed to report should I which to do so. Clearly Mecedez Benz does not need anyone who does not have Client Orientation skills. I really need help because she did not even promise to reapply for new documents for my paid up beautiful car.
