The beggining of our nightmare

On the 26th of February 2021 my husband and I bought a car 2009 X6 cash at auto investments centurion and was assisted by a one if their sales man who did a great job by making sure we purchase that car with no doubt. All the paper work was done and dusted the same day and they requested that we give them time to do the touching ups for us to make sure the car is spotless when delivered to us and we gladly gave them a go ahead to to that not knowing we will wait few more weeks for the car to be delivered to us. Patiently so we waited. A month later on the 25th of March we received a call to come fetch the car,as much as we where not happy with the weeks we waited,we where finally happy that our baby is finally coming home not knowing that it was the begging of our nightmare. The very same day as we where driving home we discovered that the car's suspension is malfunctioning which makes it difficult and uncomfortable for one to drive that car and we immediately notified the sales man and he advised us to return the car for thorough inspection of which we did. The car was again back the dealership for another 3 weeks and patiently so we where called to come ferc the car on the 17th April 2021. The 20th of April was my first day driving my car with excitement and guess what? I got stucked at the parking lot and the car indicated that there was something wrong with the hand brakes which we where never notified about. I waited patiently and frustrated so for service until my husband came to my rescue and the car was again and again towed back to the dealership for repair. This time we where so furious and escalated the manner to a very rude sales manager by the name of Riaan who assured us that everything will be fixed as soon as possible and never had the decency to even apologize to us for the countless inconvenience. The sales man made this his baby by apologizing on behalf of the company which for us spoke volumes and showed remorse which hi manager failed to do. We finally got the car back after few days and we where assured that the car was now 100% perfect as said. We coutlesly suggested that they either give us another car of the same value or our refund rather but our request was never reviewed till date. Few days later the car couldn't star nor switch on and again and again and again the car was back at the dealership which was discovered that the battery was toooo old and got replaced. As we speak the car is still not in out position and Mr Riaan is also not taking our matter seriously at all. Why would we buy a car cash if we didn't need one? Does this company know how frustrating is this for human beings? Till today am without a car and it seems like the dealership doesn't at all care but care for the sale they got? We feel cheated and ripped and ****** and not forgetting disrespected by such a big company. Today I called the sales manager Riaan who rudely spoken to me and never apologized for any of the inconvenienced caused. How does he expects us to keep smiling to them after all this trouble. Hello Peter please intervene. We are lost for words
