Integra Motors has no integrity!

At the end of Dec I signed my vehicle over to Integra Motors Roodepoort after being contacted by them to assist in selling it. On the 28th of Feb I was notified that they had found a buyer for my vehicle but that I needed to drop my price and we agreed on a new reduced price. I had put it on email as they requested. On the 1st of March I was notified that it was ready for delivery. With much delay from the new buyer the vehicle was delivered on the 12th of March and more updated documentation was requested from me which I sent the same day. I was then told almost daily with me nagging for answers that they had to wait for the CEO to come sign the documents before it could go to finance. On the 20th of March I was told that that I needed to pay the shortfall first before they can make the payment of the agreed amount which I really didn't understand as we had a fixed amount agreement and if they did not pay within 5 days they settlement would change anyway and I will have to keep paying in the difference. However I paid the shortfall anyway and requested they they settle the account before the 25th so that I could have the account settled and the debit order stopped to prevent any negative impact on my bank account. Needless to say nothing was done I was asked for another new settlement letter from the bank which I sent again and on the 27th of March I was told that the payments would be made on that day and as you could guess nothing has been done or paid. I had sent a mail to the CEO with no response on my complaint. My vehicle is being driven around on my name since the 12th by the new buyer but no one cares. Integra Motors claim to have integrity but nothing about the way I have been dealt with has been done with integrity. I have requested proof of the sale going through or proof that the vehicle is insured but I'm just being ignored.
