Appstle℠ Bundles App & Upsells

Customer service doesn't understand any concern I try to address with them related to the status of my individual products and how to best utilize their app to prevent customers adding them to their carts. Even with screenshots and detailed explanations, they are no help. I've wasted too much time with their support only to have them request a zoom that I also cannot understand what is being conveyed due to language barrier.
