Nissan Woodmead - Con Artists!

My husband and his business partner are so frustrated and at their wits end, that I am writing to Nissan South Africa, to make you aware of the despicable service received by Nissan Woodmead. My husband and business partner purchased two Almera demo models from Salesman Ryno in February 2015. Firstly, the wrong cars were given to my husband & business partner! Then the cars were in poor condition with paint peeling and scratches on the car, when it was promised to be removed. Ryno promised that the registration costs would be absorbed by the dealership and then included it in the financing of the vehicle without disclosing it! The wrong spare keys were given for the cars! And to top it all off...one the cars is not roadworthy yet AND we are still waiting for the roadworthy certificate TWO WEEKS later! When this was raised with the dealer manager Jaco, he just laughed and said well you should have come straight to me! This is completely unacceptable. We feel as though we have been completely conned...Promises have been made and continuously broken by Nissan Woodmead. When given the opportunity to resolve the matters, Woodmead declined. Would Nissan SA find this acceptable?
