Bad Customer Service

I had waited more 2 weeks for a specific vehicle and deal was given to the sales person to handle this sale. As the customer I had to follow up with him and when the vehicle eventually arrive, we had made arrangements for one of his colleagues to show me the car and have it locked. When I arrived to view the vehicle, the colleague was no way to be found, the vehicle was unlocked and the agreed Smash & Grab was not done. So I called the Sales Person and he in turn gave me a bad attitude stating that \he is in the business of 25 years and knows that I am finding faults and that there are others waiting for this vehicle if don't want it"This I felt unsettling as I made my way to the dealership in his absence and done follow ups"
