It’s nice to meet you. I am sorry that you are mistakenly seeing that notice. I will help you get to the bottom of this.
Would you mind answering a few questions so I can zero in on the solution?
What is the domain for the website showing this error?
Is this regarding a license for WooCommerce Tickets?
We actually do not show any record of your purchasing a license for WooCommerce Tickets from this account. But sometimes users register a second account on our website. If you think you might have a second account, could you provide the username or email addresses you think would be associated with it? Or perhaps the purchase receipt we would have emailed you when the order was processed? You can share this information privately via email with support @ this website.
#997173 was an agency renewal for Community Events and thus a different license key than the one you shared. (I redacted that from your post so no one tried to add sites to your license.)
Did you wish to renew Events Calendar Pro instead of Community? If so I can get those exchanged for you no problem.
Thanks again for all the info, really helped get to the bottom of this fast.
