Disgusted in the service

I bought my vehicle from hyundai Boksburg in August 2019 on the day I collected my car i was told my spare keys is still on it's way but i would get it next week with my number plates. From September I had to keep following up and ask when my number plates and key would be ready. I was told 3 times everything is there then I get there and Its not I sent my mom on another day aswell and she came back with another permit as it wasn't there again. In October 2019 I had to take the car back again for roadworthy the second time as someone didnt do what they were supposed. My front righr tyres would also go flat very quickly I had it checked for slow punctures 4 times never finding it. Some times I could swear i hear what sounds like a card in a bike spike or rubber on rubber but then it foes away again my dad climbed under the car and couldn't see anything in the wheel the radio would also just turn to different stations while I'm driving. I then tried to arrange that they tell me when my number plates would be ready so I can book my car in the same day to no avail they kept messing me around eventually to the point where the permit expired again. I have spoken to Jaco, sean, margo and Jp at hyundai about the outstanding docs. Finally got a call telling me all is ready again for there only to find only my license disc no spare key no number plates the lady promised to order them and called me the next day to say she has them I asked to give it to jp as he needs to still give me my key. This was end November! On 5 Dec I emailed the Manager again to say I still dont have a key and if they cant find it my car has to come back so they canr make a spare I have not received any feedback since then I also tried calling to make a booking twice I am put through to services who stranfers me to bookings and I am kept being transferred back to the same lady. Now there is a noise on the right wheel rattling and knocking I called customer service and asked for help and told the lady the noise is getting worse and no one is responding to me! I went to the garage to fill up again last week and asked they check again for slow puncture eventually the guy said he would put my spare on for me as he cant find a slow puncture and I could take it in when we took the rim off the whole rim is dented and rusted! That's the noise! That rim must have hit a huge pothole or accident and the tires was changed as the tire is fine ! I emailed on Hyundai's website also 3 days ago no one has responded even after receiving the confirmation email. I then called customer service the lady asked me my reg number and I told her I'm driving cant check she said she would contact the dealer principal and get back to me problem is she didnt take any of my details she only knows I bought my car from hyundai boksburg no contact number or I'd number or other details taken and needless to say I have had no feedback. I told the lady this is becoming a problem as the noise on the left is getting louder and I feel in on my steering wheel now too! I am not willing to pay for someone else's bad driving and wear and tear but a slightly new vehicle to ensure that I don't need to pay anything for at least 6 months to a year ! If the vehicle went through the numerous point check why didnt any notice the bent rim?
