Ford Credit and absa vehicle financing are ****s

After having paid off my car 4 years ago I was told to collect my Natis form. Unbeknownst to me it was the wrong paper work. Now I am trying to sell the car and was told it’s the wrong papers. I have been trying to get the correct papers from them, basically been **** to about it being delivered. I am tired and frustrated and I hate ABSA and Ford Credit with a deep seated passion
