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!
