Ordersify: Restocked Alerts

Slow service and app is not working. Been trying to get a hold of them for the past 24 hours, but no one is replying back to me. My own developer integrated the app for me, but when testing the app with multiple languages (templates inside app) then it doesnt work. The app only sends the default alert notification template, even though you have made your own language templates in their app. I need this fixed!
