Bulk Edit by Webyze

Hello,
Shopify automatically charges you if you leave apps installed. In your case, you only uninstalled the app after the trial period which is why Shopify billed your credit card.
When you emailed us, we told you that as a figure of good faith, we have sent you a app credits that you can use to make that payment and get that first month of usage for free.

Let us know if there is something more that we can do.

Cheers,
Webyze Support
