BAD SERVICE EVER!

I contacted Hyundai in Germiston trying to find out when can I take my car for service. I was told to come personally to germiston. when I got there Zack told me that they have a new system and the system doesnt show that i had brought my car for 70 000 k . I was surprised because i knew that i had brought it in. he kept on checking and telling me that i had serviced my car at Sandton, i then told him that I have never serviced my car there eventually he realised that he was checking the incorrect system. H e told me right there that he will investigate and come back to me. 2 weeks passed without any feedback from Zack. I called and reminded him about the promise he made to call me ,he was so loud and told me that im a lier that i had said that i will come to hyundai. I told him that i do not have the time to be visiting hyundai , i work and i study.I also told him that if he doesnt attend to this i will escalate it. he promise to send me the email sadly another week has passed without hearing from him.<br> <br> This man doesnt care about good service to hyundai. He even forgets conversations he made with clients!!!
