KAIZU review for Koala Bundles Volume Discounts

Not responsive. Hard to reach out. We tried to use their app thinking their app is better than others and even subsribed to them, at first, i saw a drop in our conversion. And I was wondering what is the problem. After few weeks, I received a feedback that why is our product is tagged as SOLD OUT even though I checked, we have that inventory. And we tried to click the continuous selling but still not working. I do not recommend this, we;ve wasted a lot of money!
