Poor service & damaged goods

I saw a Bakkie I wanted to buy on Gumtree. I contacted them and arranged my own Finance. The promsied to send me a quote, but they never did. Only after 3 days of calling did i eventually get a quote. Then came the delivery problem. 1st they promised to deliver the Monday, then the Tuesday then the Wednesday. I offered to collect and they must then give me a reduction on teh delivery costs. They refused the reduction on delivery cost and insisted on delivering the vehicle to me. Then they said i mist register teh vehicle and put on number plates and they will refund me. So I did, and i emailed them the two invoices and to date I have not been refunded.They refused to deliver until i signed the delivery note even though they had the letter from the bank conforming that finance is approved. Then they wanted me to pay my deposit, even before i have seen or taken delivery. Eventually the Bakkie was delivered the Wednesday and immediately the sales guy, Adam Young, pointed out mistakes and rust on the bakkie and said that next time i am in George they will fix it. He also gave an invoice as proof that teh vehicle was serviced and on the quote was the items such as fanbelt and filters and oil. That meant I have to travel 140km to them to have it fixed and they could have fixed it before selling it. How cheap can you be. I took delivery and teh very next morning i saw an oil leak. 1st Question how did this Bakkie passed the roadworthy test with a chip in the windscreen and an oil leak. I called immediately and they said the next time i am in George they will fix it. 2 Days later, the fan belt started making a noise when it was cold. I called Adam to inform him of the problem and he said they will check it next time i am in George. Here there is still no effort from them to try and sort it out. 2 Weeks later I traveled to PE and I stopped at George and gave them the Bakkie to sort out. Adam promised it would be done by 14h00, then it got 14h30 and the eventually arrived at 15h00. He then said they know what the oil leak is, but could not fix it. It was the seal between the gearbox and the engin and that they needed a whole day to sort this out. Again the same, next time I come to George bring it to them. He also informed me that they put the wrong fanbelt on and that next time i come to George, they will replace it. I ended up driving to PE with the leak and noise. On my return from PE on the Friday I called Adam and said that the fanbelt is permanently making a noise and that enough is enough. They must collect the bakkie from my home and sort it out. He promises to collect the Monday. He never did and when i called him Monday afternoon, he said that he will call me on Tuesday. He never called on Tuesday and when i called him Tuesday afternoon he said that he will collect wednesday morning. Tomorrow is wednesday and i will see if the collect, and i am still waiting on my refund.
