Delivery fee charged and I collected the vehicle :-(

I would like to express my disappointment in a company I thought was one of the best, Hyundai. I purchase a brand-new Hyundai Exter on the 08-08-2025. I must say I am very happy with the vehicle. What I'm not happy about is the fact,1stly that i need to wait so long for number plates, 2ndly when they sent out a guy to come and put the plates on at my house lastnite,which wasn't a problem, but he didn't even have a rivet gun with him and said he will come tonight with a rivet gun. Then after all that, i received my invoice only yesterday(21-08-2025),and to my surprise, i was charged over R5000 for delivery fee. I called the Bellville branch where I made the purchase to query the fee i was charged because i was confused why they are charging me a delivery fee when i fetched the vehicle myself. I then called the salesperson who assisted me when i did the purchase to query this delivery fee, she told me its a standard fee Hyundai charges all the clients. My question still is why???? She couldn't answer me and said she will get back to me today. I want Hyundai to remove this delivery fee they want me to pay coz I dont see why i should pay that.
