Central Wisconsin Ginseng Farm review for Assortion: Upsell & Bundles

I was charged $20 for a “1 usage fee” even though I uninstalled the app within the trial period. I contacted customer service through live chat to request a refund, and the representative said he would ask the billing department to process it. However, one month later, I still haven’t received a refund. I don’t understand how this app has a 4.8/5 rating with such poor business practices.
