Extremely disappointing service which I never expected for Motus

Motus Nelspruit advertised a Renault Kwid 2024 model for R134 900- with 6564km's . On Tuesday morning early I phoned the branch and spoke to Thami who at the time was very helpful. He sent me the quote and 10H10 I sent the email will all documentation required plus proof of payment for this cash deal. He then started telling me that he just need to check the kilometer because a staff member drives this car and need to check the kilometers. I said I'm fine with that it is natural that a demo model is driven and kilometers will be slightly more. By the afternoon he had not sent me the paper work because "he still wanted to check the kilometers". Next thing this car is no longer available because it's "been in an accident". They going to try and get me another vehicle and I must give them until Friday. The only time I received any feedback was if I phoned them, not once did they even phone me and offer me anything else, yet they keeping my money all this time. By Friday afternoon when I had had enough I phoned I phoned Thami AGAIN!! He then sent me an email tell me they will refund my money. I understand from a previous review that this is not the first time they do this. I am now insisting on my money back in my account with interest as I await to see this happen.
