Bad after service for rent to own customers at Car King Newlands

Horrible after service. They are only good when they need you to sign a rent to own but once signed you are on your own. I took a Volvo CX90 which I purchased on a rent to own agreement. The car had an oil leak problem when i signed the deal and I informed them about it. Paid 2.5K service recently only for oil change and oil filter, then I was instructed to bring it back for an oil leak fix. Was charged another 2.2K for the problem they were aware of and when I noted this arrogant, disrespectful individual called Morne refused to release the car unless the invoice is settled. Am highly disappointed with this treatment and feel they are only after squeezing money from clients. Their interaction with me was not professional. So am not sure who will see this but I will advice that you avoid Car King at Newlands, especially this Morne.
