BMW Worst customer service

So i had my turbo blow on my bmw 1 series and Northcliff Auto BMW was the nearest dealer for my car to get towed too, to get repaired. I stood in a line of three people the first person in the queue was a worker from bmw who was talking smack to service advisor Carol so i patiently waited for their heated conversation to end and then when i had to get helped i was not greeted to start with and after a few minutes my car was booked in. i had a loan car from bmw assist but they only loan the car for about 5 days, so from the second day of my car being there i phoned in numerous times and spoke to Carol the service advisor to find out if they started working on my car and she said they have not started yet which i understood then i then phoned in three days later and they still never started on my car so i lost it abit and i spoke to the DP which knows nothing about cars or how they get fixed he said he will look into it he called me a day later and said they will fix the car in one day which he **** because who does a turbo and a cat in one day when they never ordered the parts then he had the mechanic call me to explain to me what needs to be done on the car and at this time i never had transport because bmw assist took their loan car back and here i was back to taxis taking my one year old baby girl to creche with a taxi because bmw northcliff could not even provide me with a loan car. After two days of me fighting with them they decided to give me a loan car while they were fixing my car. i fetched my car on a saturday with skeleton stuff at the service desk, some random lady behind the counter which did not look like a service provider gave the keys to my car and i left a few days later i realised there's now a rattling sound by my dash near the turbo so i called in numerous times and the reception just says she will take a message for Carol the service advisor which she takes but Carol never got back to me ever since 2 months i'm still waiting for her to return my call. I even ended up taking my car to another bmw to resolve their mess.

I think that this bmw dealer is the worst in joburg and that DP and service advisors lack the s****s and knowledge of their product dealers like these makes a mess of the bmw name in SA as i am a bmw fanatic i had about 5 beemers from old to new and this beemer will be my last because if this is the quality of service we getting i can rather buy a cheaper car and deal with ****ty service.
