BMW SMG DURBAN

The service manager from smg bmw durban customer service is disgusting and pathetic and is a bully to customers... I am the owner of a bmw m4 and i had my car booked in as there was a problem with the air conditioning and rental car was given to me until my car be fixed, when i picked up my vehicle i had heard a rattle in the car which i was not happy about as i spent R1. 2mil on that vehicle and ideally you would want to have it repaired ASAP. I advised the service manager before i could take my car from the dealership and he was rather aggressive in the manner he spoke stating that i need to have my car rebooked in which is again an inconvenience to me as i have a very demanding job that requires alot of my time. Mr Govender had then been contacted again and i advised him that i want to bring my car in tomorrow Saturday and they need to tend to it and i will require a courtesy car to use on the weekend as i have elderly parents who are physically unwell and in the event of an emergency i will require a vehicle. Mr Govender had then made awful excuses such as they are skeleton staffed on weekends and my car will only be tended to on Monday which i can not be without a vehicle as i go to different hospitals and it is vital that i have a car! Mr Govender then said that BMW SA does not give a courtesy car for rattles in the car as the car is still drivable when i had asked him if he had an assessment done on the car he became very evasive and answered No. I had then asked him to email me stating that as per his knowledge that the car is drivable and that BMW SA does not give a courtesy car for such he had promised to email me and took my email address but failed to keep to his promise he had also said that when i can get my car in he will get a courtesy car for me to use so if bmw sa dont pay for a courtesy car that i required today how are they going to get a car for me if i had booked my car in? Which i know he was lien and was so disrespectful talking over my voice. I had asked him to outsource a car from another bmw he said he can't. I asked him for his bmw he said he can't yet its a company car.... I will be taking this up further as his behaviour was unacceptable and his lies of emailing me back
