Poor customer service from pre-owned vehicle sales manager

I have been taking my car to Hyundai Somerset West for years and this has to be the worst service I have ever received. About a month ago i called the dealership because I needed an evaluation on my car. They advised I speak to Justin Swarts. It took me 3 days to get a hold of him. I left messages and he never called back. Eventually when we spoke he asked me to whatsapp my details and he will send me the evaluation. I reached out 3 days later and he said that he sent to me but he was obviously lying. I have been following up with him twice every week and he has been ignoring me and blue ticking me on Whatsapp. I even emailed the dealer principal and he aswell has not gotten back to me. For Justin to provide a poor service is disgusting for a manager. You giving this branch a bad name. Anyway i will be taking my business to Hyundai in Stellenbosch.
