Bad service and Unprofessional

i booked my vehicle for a service at Kempster Ford. On the 6th i advised the consultant that there is something wrong with my air-conditioner even if its switched off there is warm air coming through the vents. The consultant told me that they can service the vehicle today which will take the whole day because they also have vehicles which was booked in from Monday. They will only start with cars that are booked in today at 10:30. i said to him if my vehicle will over night because of the aircon problem can you kindly provide me with a loan vehicle which he indicated that they preference to customers who purchase their vehicles at their branch. To me Ford is a brand which should make their customer all over the world. I than contact the ford customer care centre which the agent connect me with the the dealer where my vehicle is currently . They said the manager is busy in a meeting and will contact me once his available. The manager contact me and i explained to him i dont know what wrong with the vehicle and i take it as a risk to drive with my 3 year old son in a car which does not have a aircon and there is hot air which can be a danger to my son and i dont want to put his life in danger. He told me that they have to book an appointment with the air condition place which he dont know when the appointment will be. Which advise so i must put my child life in danger, i request i loan vehicle until they can resolve the matter which he said unfortunately he cannot make a plan that not how things work if iam not happy they can stop the service an d i can take my vehicle to another dealer. How can you treat a customer in this manner. i told my car is new how can it give me problems he said that car is far from new. than i was asked where was my car serviced all the years i advised him in Cape Town and my agents treated my in a professional manner they would also provided me with an alternate mode of transport if this was the case. I am a resident of Durban now so will i be treated by Ford like this for the next few years. I should rather drive with the vehicle until something happen that i get punished or they should just pass the buck like the manager want to get ride of me. He does not have the s**** to resolve a matter. I could have been a potential customer for a new vehicle in the future but him and his staff changed my view.
