Complaint no service provided

Hi I am so disappointed with BMW service, I own 3 cars with them recently bought JCW countryman. They took my car in for servicing told me that the parts were being ordered at germany and will take 2 weeks to be delivered. I spoke to the service consultant that can't they arrange a courtesy car since I use my car to see clients. The consultant agreed that they can hire a car for me I must pay R1400 for the hired car and they will refund when I drop it off, she said she will be speaking with her manager to authorize this. she then came back and said the manager said I cannot get that option as my car is a 2013 old model even though it is under motor plan with 40000 kilometres. They suggested to buy a new battery and remove the dead component and suggested I drive the car without being fully fixed. I refused to take a car which is not fully fixed. I suffered a great deal from BMW for the past 2 weeks without a car. They called me today to say I must bring back the car while the car is parked at their yard which made me wonder if my car is even safe with them. I am highly disappointed with the way my case was handled while I have a valid motor plan on my vehicle. I only bought the car last year November. I am very disappointed with the service at BMW MIDRAND.
