Charged for Nothing! He did not know what he was doing

Took my Garmin Vivo active 3 because it had a red exclamation that would not go away and they could not help me and still charged me R200. They said the problem was with Garmin Server and it was not there. The guy just did not know what he was doing and he charged me for that. I eventually sorted the problem myself by rebooting the watch. that’s all he needed to do. Just be carefull when you take your watch to Navworld they are not an official authorized service provider so one might loose the warranty on the watche.
