Horrible customer service. Wait atleast 1 year for car to be fixed

Hyundai Nelspruit is the pits. I went to the dealership close to 5 times this year alone, today I went back again for a problem they had supposedly fixed. Around June/July this year I incidentally discovered that my hooter isn't working, went to Hyundai, they ordered the parts which took forever/more than two months( by the way, they never communicate, when you call you'll be transferred to offices where no one answers the phone. A week ago while driving on the N1, was in between 2 trucks at the tollgate, trying to alert the front truck not to reverse because there's another truck behind me, only to discover that they hooter "they fixed" isn't working. Today they tell me that it's an electrical problem that's not in their control, they'll order the parts next week Tuesday, which will take half a year to get delivered. Imagine driving around in south African roads without a hooter, what am I going to tell the traffic cops??? Not even roads only but just mere parking lots. Hyundai customer service is just full of Nonsense, Nelspruit one has been the worst . Maybe because I'm black and young that's why they're disregarding/minimizing my car problems. It's really unfair what they're doing to customers. Such shifty service is unacceptable . My safety is currently compromised.
