Hyundai Customer Service in the Service Department

We took our car into Hyundai Zambezi 5 months ago within our service plan to fix our reverse camera on our i20. 5 months later the issue is still not fixed after having to take the car in about 7 times without being offered a loan car for the inconvenience even after expressing our concerns and explaining that the situation is getting ridiculous. Hyundai Zambezi does no effort from their side in terms of customer service. We only get feedback on the progress if we call them and then the person on the line is annoyed with us for calling so much. There's no "sorry for the wait" or anything in that direction, it's just as if we are a major inconvenience for them. We were going to buy our next car from Hyundai as well but thanks to this experience, we will never drive a Hyundai again and will share this experience with anyone who asks. The sales service is great, but once they get you reeled in, that's where it stops. Wade and his team in the service department are extremely unprofessional and ***********. If this is the kind of people that Hyundai employ and approve of, this is easily the worst car brand in South Africa.
