DISGUSTED BY HYUNDAI UMHLANGA AND NON SERVICE!

I phoned Hyundai Umhlanga because my Hyundai i10 radio has not been working properly for about a week and wanted to make sure it was still under warranty before I bring it to them to have it fixed. The lady took all my details of the vehicle and told me it was still under warranty until end August 2018. I booked it ion for the radio to be fixed. I arrive at Hyundai in Umhlanga this morning, fighting my way through peak hour traffic and then the guy comes to me and says I see your vehicle is checked in for the radio, so I say yes, it's still under warranty and start to explain what is wrong with the radio when he tells me sorry the radio is only covered for 3 years and so is no longer covered? WHY COULDN'T THE PERSON TELL ME THAT WHEN I CALLED TO ENQUIRE ABOUT THE WARRANTY??? Why did I have to waste my time and petrol to drive there for NOTHING????? I asked if someone could just see if there's a lose wire and was told NO! They charge R680 an hour for labour so could cost me a small fortune to sort this out. I angrily drove away and will reconsider if I ever return there.
