Garmin watch malfunction, a month, and no update or replies to my emails

From day 1, my Garmin watch was giving problems during exercise, restarting unexpectedly. I've since sent the device back (via courier) to Garmin. Firstly, I had to plead just to get a confirmation that they have received the device, after many emails and calls. They eventually confirmed receipt for 31 Aug. Today (2 Oct), I haven't received any feedback or replies yet, despite many follow up emails. Does anyone know if Garmin South Africa still exists?
