False adverti*****t

First week of December 2015 I saw the adverti*****t of Imperial motor/Uber for Ford Focus deal price was R171 000 including vat. I apply through the bank and bank approved the finance. Then it was time to deliver they always say they are waiting for approval from head office before they can deliver a car. It went on until this week when they say the deal was advertised by mistake. Now I have been waiting for than 3 months to be delivered. Every day I'm losing money because I wanted the car for business. Can you please ask the dealer to deliver according to the deal they have Advertised
