Quantity X ‑ Quantity Breaks

I am extremely disappointed with this app and its customer service. The developers are clearly incompetent as they couldn't resolve my issue. The app listed my products at a price of $0, resulting in over 15 free orders. When I contacted customer service, they initially tried to blame my discounts. After testing all hypotheses, it became clear that the problem was with the app itself. The support team then simply advised me to uninstall and abandon the app due to their lack of competence in resolving the issue. This app, although promising, does not work correctly and the developers are incompetent. In just one day, I suffered huge losses and received seven new negative reviews from customers who managed to access my store and purchase items for free. Beware, I strongly do not recommend this app and its terrible support.
