Garmin Forerunner 735 XT Won't switch on

Good Day

Can someone from Garmin please contact me. I bought my Garmin Forerunner 735 XT at Sportsman's Warehouse in July 2019. I have ran and exercised with it for a year and 3 months. It won't switch on now, the screen is blank. And it was fully charged the previous day.

I have sent it away with Sportsman's Warehouse, but I am unhappy with the response I received. As I don't want to pay a huge amount of repairs or for a new watch, as the watch is only 1 years old basically.

Please contact me please
