Charming Beads review for Shopify Marketplace Connect

Was working perfect for weeks and then suddenly got oversells on ebay. The polices that were previously showing against my listings had gone. Spoke with Mark L - an extremely arrogant person who insisted their perfect app could not have possibly lost the links. Well I hadn't touched this stupid app for weeks and the links were lost without my intervention. So if it wasn't me and according to Mark L impossible to be their app, then I guess it was an act of god or something daft then, huh!?
