Vw dealer problems

I bought a car at a vw dealer in the month of september 2021 and its now november 2021 in this 3 months having the car i have experiance 5 problems this first one occured 4 days after purchused date wich was a engine oil leak then i send pictures of everything and the said i must bring back the car for repair or to check wich i did the car then stayed with them for 5 days.They solved that oil leak...after that warning lights came on on the dash i phoned them again and send pictures once again i had to send back the car and it took another 5days for repair after that the central lock button stoped working and also the button that adjust the lights have in fact never worked since you can only see at night if working or not then i had to contact them again and they said those are not their problem but after a while agree to give me the parts thats needed to repair but i then had to pay the labour for that work(i contacted vw south africa and they could do nothing nothing!)..and now a airbag light came on that stays on while driving and AGAIN i have an engine oil leak...please i need help???
