I have purchased my new car Atos from Hyundai Sandton Branch on the 30th April 2022, they gave me temporary registration. After it had expired I enquired about my license plate and disk they told me I will get it on the 23rd of May till today. Everytime I call I get excuses. 21 days has passed and the second temporary registration they gave me is expiring soon on the 15th of this month
