BMW Centurion plays games

On saturday (28/6/2025) I visited the BMW in Centurion with the intent on looking at a 218 Gran Coupe to purchase. Firstly, we walked around a few times with no service. The two white men at the sales area did not even bother to look up until we were literally in front of one of them's desk asking for help. We looked at an entry version on the floor and then engaged further for a fully spec'ed one. A profile was set up and i was told that they can offer a R15k discount provided i made a decision within the month of June. On monday i was all set up to transact only to be told the R15k doesn't apply to that specific car and the reason didn't make sense. I was surprised that the salesman did not know their own rules. So i switched to the indian saleman and was told they will look for something and they would make a plan for a discount. That was monday - no real options were presented. On tuesday my brother went there personally and complained and was told that they have a proposal and it would be sent. It wasn't until tuesday around 5pm when i messaged him and asked if they are serious about helping me or not. Then immediately i was sent the offer for the car i wanted on saturday and was told the R15k is still to be app**** but he'll ask for an extra discount and come back to me on wednesday. Today (wednesday) they come back say no discount will be offered, the discount was only applicable to june. Then there were stories that since the vehicle was in cape town it would have had to be delivered by the last day of the month at the dealership which was not in my favour. On principle i refuse to purchase from such a biased an unprofessional dealership that seems to change their story based on your face and the day. I know for a fact many colleagues that recommended this dealership and mentioned the discount and that is not based on a specific point in time. I am still wanting to purchase my fully spec'd vehicle but this is unacceptable. BMW SA must please explain their rules on discounts in a consistent manner and please tell me where in Pta is your unbiased dealership. And i am using the word unbiased but i actually mean something very specific. if my method of payment is the reason then also be clear upfront.
