Frustrated Mini Cooper client

I would like to ask what must we do in the Easterncape, Port Elizabeth to be precise, Mini Cooper doesn't have a spare wheel and when it was sold to us we told that we can just call their help desk and we will be assisted and given a spare wheel for atleast 5 days ...we had the car for almost 3 years now and the experience with Mini after service is pathetic.The people that are suppose to help you are some what not empathetic and dont understand your frustration...I'm appealing to Mini to take their car sothat we can be able to get reliable vehicle
