WHSL-WR review for QuickBooks Desktop by Parex

I have been using this app for several years, very few issues until now. Orders are not syncing even after multiple attempts. The biggest disappointment is there lack of customer service, they are on the other side of the world so any resolution is 12 hours away at a minimum. They seem highly focused on completing the service call then they are at actually focusing on the issue to ensure the app is functioning properly. I sent screen shots today, still waiting for answers!!
