arrogance and rudeness from the line manager

I bought a car last month (March) at Webuycars The Dome, and on the add they said it has a spare key. I went to pick up the car on the 22nd of March 2024 and the was no spare key provided and I immediately advised the sales person ( Liam van wyk )that the car was advertised with a spare key and he didn't give me the spare key. I also advised the financial lady Jeanne P. They promised to do a follow-up with the line manager. On the 11th of April i sent Jeanne P an email doing a follow-up with regards to the spare key and she sent an email to Liam, then the next day I called Liam and he told me that he is going to do a follow-up with his manager as the manager was busy. Today i called again and was given the managers number and his name is Ruan, I called him and explained to him what had transpired and he advised me that I should bring the car to the branch so that he will call his locksmith and get a quotation and cut the key, that's where me and him had a problem , because I told him I can't come to the branch because when I picked the car the spare key was supposed to be provided on the day. I also advised him of my daily trips and it's highly impossible for me to bring the car to the, he then said I should take the matter to the ombudsman, he spoke to me in a manner that I did not appreciate, he spoke to me like he was speaking to a small boy, his arrogance and rudeness towards me is appalling.
