WORST SERVICE EVER

I took my car into Hyundai Paardeneiland to get my Hyundai radio fixed. They then gave me a radio that was even worse than the first one. Then I took it back and got a radio that was apparently ordered from China. That radio isn't working. Now my warranty is up and now I have to pay for a new radio because HYUNDAI PAARDENEILAND IS INCAPABLE OF FIXING ANYTHING. The Hyundai in Johannesburg gave my sister a brand new radio which wasn't the original Hyundai radio. So why couldn't the Hyundai in Paardeneiland do the samd thing? I contacted Hyundai to work out this problem and Leon told me he will get back to me along with 2 other workers. Never heard back after countless calls. Will NEVER recommend them. I will make sure I'm heard through newspaper and social media.
