Is a first-time buyer of a car I'm very disappointed.

As the first time buyer of a vehicle. I was excited that I got approved but I qualify for a for a vehicle. Kia roodepoort approve me for a C4 citron 2016 i was happy I loved the car. 1st of November I went to the dealership to collect the car it was perfect then December it started to saying service is due. I took it to citron dealership in January for a service I paid about R8000 for the service. I've never enjoyed the car now vehicle wants to be repaired. I have not even drive the car for more than 5 months and already I'm spending more on the car I'm not happy about the service how could they sell a car that it's not in good condition just to give it to someone to be a problem. I regret the day I app**** for finance at roodepoort they given me a greater problem to deal with I'm losing money month and in and out fixing the car that I've not even enjoyed driving for 5 months
