Super Dog Accessories review for Royal Mail Shipping Extension

DO NOT DOWNLOAD THIS APP! The app doesn't work accurately if you post your items in different sized boxes. There is no support and no way to cancel the subscription. It isn't showing up in my app list so i can't delete it but it is showing up in my active subscriptions so i know i will be charged. ABSOLUTE SCAM. I will be contacting Shopify about this to get them to remove the app for me.
