Bad, terrible and pathetic service

I had the most unpleasant experience, I made s bid on a car on Monday the 26 August for a car and won the bid. A guy by the name of Isaac called wanted us to proceed. I went for a test drive on Tuesday but was bot there, however referred to a guy called Njabulo his colleague who helped us test drive the car. The car left door wasn't opening, the car was not road worthy so Njabulo escalated the query to head office. Head office told me Njabulo shouldn't but instead he should have spoken to a manager to assist me yo look gor another car. Isaac returned from work and told me to look for another car because it would look bad on him sitting with an unfinished deal. I've been looking since Tuesday but I felt as though I was bothering him when I showed him the cars I was looking for because he kept telling me me that I'm not the only client as he's got in Walk in client. Today at 12:48 I sent him a pic of another car asking him to check If they still have so I can come through test drive, pay and seal the deal but he said he will until 15:30 when their Head office called me to check the progress. I honestly told ghe lady what has been going on and she called Isaac whilst I was online, before I knew it Isaac was shouting at me telling me to do whatever I want. He was going on at me as if I called Head and kept on defending myself as if I did something that I didn't call Head but instead they called me. He reiterated that I'm not the only client he's helping and dropped the phone in my ear. I'm so traumatized. I called Head office they transfered me to his manager who told me I overwork myself , who wasn't even I interested but cut me short by saying "we will cancel the deal and refund" I find time very rude as well. I regret attempting buying a car at We Buy Car Germiston. Isaac is blutently rude with an abusive tone
