Every one makes mistakes.....Okay, we have a simple issue. We're using your paid plugin on our website, which you can verify. We commissioned and paid the website maker for the task last year. You can verify this by contacting the website builder. We no longer utilize the services of the website builder as we maintain the website ourselves. We've sent the original invoice to you, which you can verify as well. What's missing is a purchase email, but we don't have one. That's why you're refusing to provide assistance. We've accepted that we won't receive any service. We've been struggling for over 1.5 months and can't even update, causing the plugin to malfunction. We're giving up. Good luck with that 265 euros.
