Pathetic Service and Misleading advertising

The most horrible experience of my life, the worst service I've received ever, not just from a dealership also from the sales person Jaques. On the 28 March 2023 I was offered a 2019 NISSAN X TRAIL 2.0 VISIA. I signed for the offer and send back to Jacques Van Der Merwe the sales, went to view the NISSAN on the 1st of April 2023, I loved the vehicle immediatley paid in a deposit of R55 000 on the vehicle immediatley. Boom Monday the 3rd of April 2023, what made the matter I had to chech up with the sales agent Monday to check if all is in order only to find out he sold me a vehicle that has already been sold but they still advertise the vehilce on their website. Lond story short they offered me a 2017 Nissan Xtrail , KM over 115000 I told the sales agent I want to think about the offer, becasuse it was an older shape. Next thing Boom the dealer principal is calling by the name of Johan and appologized for the mess they have done and want to know how can they fix the matter. I gave him and option to get me either a Nissan Xtrail 2019 or Haval jolion, he then told me on the Haval jolion I will pay an installment of R12000 deposit of R70 000, he then gave me the last opyion > Cherry Tiggo Pro 4 > Deposit R65 000, when the sales agent called me with the offere I accepted the offer but just before the sales agent drop the call I can hear them laughing at me at back. I regret the day I went through this dealership to buy a vehicle.
