I am utterly furious and disappointed with Hyndai's overall service, I profusely regret buying my car from there. They sold me a faulty brand new car in which they refuse to fix. I was given false information regarding the car, service plan of the car and warrantee. Whenever I call through regarding help for my car the staff is extremely rude over the phone and hang up the phone. They had refused to service my car numerous times because they had told me my car has not reached the 15K Kilometers Threshold. Now that my car has a factory fault from their side they simply refuse to fix the factory fault from their side and are now threatening to terminate my service plan if I do not plan to pay them R2000 Fee for them to fix the faulty car they gave me, which I have been paying graciously every month and I have never missed a payment. They had promised my car would be fixed within 2 weeks and it has not been fixed, it's been almost a month now without my car which is an inconvenience, and the courtesy car they gave me after a whole 2 weeks of me following up is extremely old with a faulty clutch posing an even greater threat for me when I'm on the road with it. Is there someone I can escalate this to as this is completely unacceptable. The company also refuses to exchange the car for a brand new one claiming that, I can only do so by paying the car afresh which is really not fair as the problem was from their side. None of this is making sense.
