Poodle World review for Recharge Subscriptions App

We briefly installed this app 18 months ago when it was free, but never actually used it. We were therefore shocked to discover that Recharge had billed $99 to our Shopify account last month. We have contacted Recharge numerous times and they have promised to refund. However, we have still not received a refund to our Shopify account. We have been back and forth between Recharge and Shopify customer services. Shopify tell them to refund us. Recharge say they will refund but the refund never materialises. We are extremely surprised that an app on Shopify is allowed to operate like this.
