BMW Vereeniging - Worst customer service

We have purchased a BMW from BMW Vereeniging about 1 year ago and the appalling service seems to continue with a delinquent sales staff, Daniel... so the new issue, we need to book our vehicle for a service at BMW Umhlanga and they cannot accept the vehicle because he did not change details on their in-house system. The vehicle still shows its under BMW Vereeriging and all he needs to do is the update of information. I've called him 3 times on Friday. 1st called to inform him and he said he will get it done now, 2nd follow up call later the same day he said he will return my call have have it sorted by 11h30. When I called to follow up again. I was informed it was done and he did not call me back because he was busy with month end. So I called BMW Umhlanga to advise all in order and they confirmed its still not done. So I called Daniel back and he refused to take my call OR reply to my email. Worst experience ever experienced from a reputable dealership. Now I sit with a 2024 modal car which I cannot drive because of this *********** BMW staff.
