Expressive DeZien review for BOOSTER AI SEO OPTIMIZER

I REMOVED YOUR APP WHY DID YOU STILL CHARGE ME? I WANT THE 55.00 REFUNDED ASAP. I read in another review "To cancel your trial period, you just need to simply uninstall the app in your Shopify admin before your trial runs out. Uninstalling the app from your store will effectively cancel your subscription." THAT IS UNTRUE. I uninstalled the app and it charged me 55.00 anyway.
