Very Bad Service from Garmin South Africa

I contacted Garmin South Africa because a watch I owned started showing dead pixels. After two attempts at contacting Garmin South Africa, I received a response. I was asked to send the device to their Rosebank offices in Johannesburg. I have not received a support ticket, nor confirmation that the device has arrived. Communication between myself and Garmin product support has stopped. I managed to get a contact number for someone called Refilwe, whom was very unhelpful and put the phone down, probably because he did not want to talk to me. I guess I have to forget about the watch? Where is the managing director of Garmin South Africa? I will never purchase a Garmin product again.
