They keep charging me $9 every single month even though I have canceled this service and have done everything I can think of to cancel it over and over again. They are stealing my money. I am calling the BBB.
UPD: we indeed charged you. I have sent you another email and asked whether you want a full refund. We are using Shopify Billing which is a bit complicated but totally transparent. You can learn about it on https://help.shopify.com/en/manual/your-account/manage-billing/your-invoice/apps. We couldn't charge you without your permission.
