Kia South Africa/Randburg

Customers service and Kia Randburg keep passing the buck. Thokozile Khumalo sent me this email on 14/6/2021: "I sent a 2nd follow up email to Farhaan this morning - I have had no feedback. I called the dealer aswell and left a message. I will keep on trying Sarie and will let you know once I get a response". Apparantly Farhaan from Kia Randburg refused to deal with this matter. I have requested that they make me an offer for the car and take it back. The offer must at least cover the current value of the car plus a refund for all extra-ordinary repairs that had to be done. On 22/6/2021 I have received the following email from Thokozile: "The dealer advised that they cannot assist or support your request for a replacement unit. Whilst we have not provided you with the outcome or request you sought, we trust that you will be reasonable and understand our decision in this regard". Is this reasonable for the consumer?
