Terrible customer service

My car was broken down and towed to the dealership. When it was approved to be fix Nissan Sa I asked Nissan northcliff for a courtesy vehicle. This is Nissan sa policy . After sales manager Jerris Hammam in a rude way told me he does not have a vehicle for me an it is not Nissan northcliff policy I can phone Nissan sa an complain if I like . When I picked my vehicle up the service advisor Gertruida Van Der Westhuizen cold a rude . I have raised the matter with Nissan Sa and they have contacted the dealership up to this day no communication from Nissan northcliff. The customer service is absolutely disgusting.
