MB Bryanston refuses to take ownership for their own mess

MB Bryanston. I booked the car in for AD Blue Light and Engine light on Weds 18 April 18. They called me later same day to inform me that, they ordered parts i will not be getting the car same day, i requested to be dropped off at Fourways from Sandton since Buses where on strike, if which i was told is not possible of which i learnt later that is possible within 10km radius. I received a call again on Thurs to inform me that i will have to pay, i sulked and agreed to pay. I received a call again and i was told, my car is ready and I was not charged all will be covered by Maintenance Plan. I was happy not to pay, until i got to the dealership where the same lady asked me to pay when i told she said is covered she disrespected me and told me i am talking RUBISH, NONSENSE and until i played her the voice clip... only then her arrogance came down and she apologized for the error of which i told her she should be a big girl and take the responsibility. She asked me to wait while she help another customer, then talk to the relationship manager... I waited for over 30min... they called me into the office where i thought that were solving the issue, only to find out that they called me in there to further waste my time and bully me by telling i am not getting the car, i will have to uber myself home. The manager even had the guts to tell me that in 3 days he will start charging me storage fee... of which i reminded him that i am not the cause of the problem, and in SA you pay the price you are told and he should stop with his bullying tactics. They refused with my car and told me to go complain... There was no sense of trying to solve the issue by to bully me around...

I am disgusted by Mercedes Benz service, i expected some professionalism and taking ownership of their own mess... I had to wait for Uber outside in the rain, it was dark and unsafe as they were closed.
