Stevvex review for Koongo: Sell on Marketplaces

Doenst work at all ! For each sale channel you need years to speak with customer support and they answer once daily and you must fix with them each channel which doesnt work at all ! I was use for years and I wrote over 1500+ emails with their customer and when we solve problem, new problem appear. This app change variants ad make them separated and system publish each variant separetly ! I used it for Wish and Amazon and this was horrible experience ! Also when Wish charged penalties, this app made me errors which costed me over 240$ in penalties ! Avoid this app at all ! I asked for refund and they didnt gave me it ! They present that Koongo has integration with marketplaces, but when you try it this doesnt work !
