Question for BMW SOUTH AFRICA - HEAD OFFICE

Who need to pay security deposit for courtesy car if my brand new (2 months old) BMW X3 is having a fault and the part is being ordered from Germany which will take 3 weeks. I am only going to get my car back in January and i don't have the R3000.00 to pay for security deposit to get that courtesy car. My car is very new and i did not put money aside for breakdowns because i did not expect that from a new car?
