Venu sq 2 stopped working - no support

We bought a Garmin Venu SQ for our daughter twenty months ago and it stopped working. We sent it in via Incredible Connection and were told that it is uneconomical to repair. We have not received any further communication from Garmin despite numerous emails. Garmin has not returned the watch to us or offered any compensation alternative. It seems like a bitter pill to swallow that an expensive watch is expected to last for a little over a year only. I would not buy a Garmin again, because there seems to be no after sales support in the case of a faulty watch.
