Syncee Premium AI Dropshipping

Using Syncee for 3 months - Support is inadequate and app is malfunctioning
For the past 2 weeks, despite correct settings (import lists set to inactive), the app continues uploading products with 0-stock variants to my store. This results in 2+ hours of daily manual cleanup work.
The scale of the problem:
26 products with 119 zero-stock variants keep re-importing
Manually deleted 7+ times - they reappear every time
Import lists confirmed inactive - app ignores the setting
Support response: Two weeks of the same copy-paste message: "Can you test? We'll have tech look into it." No investigation, no timeline, no resolution, no follow-up.
Business impact:
28+ hours wasted on manual deletions (2 hours/day × 14 days)
Polluted inventory data
Cannot trust the app's basic functionality
Half my store runs on Syncee - cannot uninstall despite app failure
This is not a minor bug - it's a core feature (import controls) completely failing. The lack of urgency from support makes it worse. I've provided screenshots, detailed reports, and clear reproduction steps. Still no fix, no ETA, just generic responses.
Would not recommend until they fix basic import controls and improve support responsiveness.
