Misinformation & extremely poor service from Ford Umgeni

Where to start? I went to the dealership on Saturday morning and asked if they had any 2019 Fiesta demos available in automatic. I was shown a vehicle and told it was the last one and asked if I'd like to go for a test drive to which my response (word for word) was, "before I drive it I'd like to know the price so I don't love the car but can't afford it". We went to the office and I was given the price of R240000. I agreed it was in my price range and we went for a drive. Afterwards I wanted the vehicle and paid R500 as a small "holding deposit" so that it couldn't be sold while my finance was approved and my insurance payout reflected in my account. Once the money was reflecting in my account on Monday I emailed to ask for the bank details so we could proceed to which their response was to let me know that they had made and error and the actual price of the car is R272000 - if I had been told this initially I would have left and continued to look for another car, as I'm a rep and not having a car is effecting my livelihood and I'm desperate to get a car since mine was written off. I still haven't received a single phone call, only emails hours apart. To add to the misery apparently the car I drove, paid a deposit for AND had finance approved for is not R272000 but it has apparently already been sold. A comedy of errors and misinformation that I'm still trying to comprehend.
