Greska's Carbon 60 review for Patch Customer Retention

Jan. 26, 2026

(posted to warn other businesses): From the moment payment was processed, the app did not work. Immediately after paying, the app redirected only to an error page. It could not be opened, accessed, or used in any way. There was no functionality available at any point. We contacted support and were told the issue would be fixed. After continued communication, they later admitted they could not fix the problem. Despite this, they continued charging us. When we formally requested a refund for an app that never worked and services that were never provided, the refund was refused. Even after requesting the refund, they continued attempting to charge us, forcing us to stop the charges through our bank. This impacted our entire company. Multiple team members experienced the same issue and will be leaving reviews to document this. Additionally, due to Shopify’s review system, we were required to reinstall the app in order to submit this review—forcing us to re-engage with a product we already knew was broken simply to warn others. Charging customers for a product that fails immediately after payment, admitting it cannot be fixed, continuing to attempt charges after a refund request, and then refusing to refund is unacceptable. Based on our experience, this app presents a serious risk for other businesses. I am not one to normally leave lengthy negative reviews. but this is the worst experience i have ever had with a Shopify app.
