Worst Customer Experience Ever!!

For a business that sells cars they suck!! I have sent 4-5 enquiries via CARS website for a vehicle I am interested in buying. Eventually I called the dealership and the number on the CARS website says it no longer exists when calling. I googled their website and called and eventually spoke to Portia. She is was too busy to talk to me and said she will call back. I’m still waiting that was yesterday. I called back again today and spoke to her again and all she said was the car is still available and put the phone down. Worst customer experience ever
