Misleading

My name is Joseph mmotong ID ********** 530087 I was looking for hyundai ix35 so I searched for it on cars.co.za I found it a the price of 138,000 the I showed interest on the car then cars.co.za forwarded me the details of the car so I called the branch to ask if they still have the car they said yes I can apply for it so I did apply for it on the 31St of January later the same day I was told that it is approved I can come on the following day I was excited about that so I told them I won't make Thursday I will come Saturday on the 3Rd then on the 3Rd I arrived at the dealer then was introduced to the financial advisor when we are busy with the advisor I was told that the car is 179,000 so I will pay something like 4500 pm and I was surprised because the car that I saw and app**** for it is 138,000 on the Internet I asked to see the car they took me to another branch when we arrive there the price on the car was 174,000 then I asked why,he said because of the shortfall on the car I want to trade in then I told him I have 20000 for the top up then I said to him I will see him next week to finalise the deal for 20000 top up then I left the place because I was confused of the price I asked him again about 138,000 he said it was pricing error so I decided to contact the branch to speak to the management only to find the manager he/she is not around but I left the complain so that they can tell him on Monday after I called my lawyer to seek for advises about the matter.
