Second hand/demo vehicle sold as "new"!

After having bought what was sold to me as a "new" vehicle, I discovered pieces of sellotape on the front bumper (clearly someone didn't do a proper job covering up their tracks). When inquiring this with the lady that sold me the vehicle, not only was Melinda Erasmus dismissive, it seemed like she thought I was making all of this up. I finally took the car to Nissan Witbank for an independent inspection and they confirmed my suspicions, stating that there was overspray visible on two different spots on the front bumper. Even after all of this I was appalled at Northcliff Nissan's refusal to resolve this matter or let alone help me understand why there was spray and body work done on the vehicle or even why it was sold to me as a brand new car. This is the worst customer service I have ever experienced, not only did they refuse to acknowledge my problem , they also even refused to assist even after I proved to them that my problem is real. I don't trust Northcliff Nissan anymore and I would advise everyone buying a "new" car from them to make certain they are not being scammed!
