Having zero luck with this product so far ..... i really like it when it works

I ordered a combustion thermostat back in February 2022. It was not working properly, and it was replaced in June of 2023 Order. But now this thermometer seems to be completely dead. The display nor my phone will find the device now and the cradle's charging light does not work so I have no idea if it is charging either. I have tried emailing support again but after two emails they are not responding.  Anyone else have issue getting help?
