Hello Karina,
I have split your response to assist you further.
Please make sure that you’re linking the right email you used when you registered on the event. You may follow this Instructional Video for more detailed steps in redeeming the discount.
You may also need to clear your browser’s cache and cookies or may use a different browser to confirm if the issue is about the browser.
If you’re experiencing the same or encountered issues, please send us a step by step screenshot using Problem Steps Recorder (PSR) starting from the troubleshooting and until you are on the page showing no discount available.
You may upload your PSR through the private message I initiated along with the requested information.
To access your private message, please refer on the image below or click on this link.

Also, ensure to attach a copy of the actual congratulatory/confirmation email of the event you attended where it shows the “To” and “From” and the Event ID.
Upon receipt, we’ll replicate the issue and forward it to our Support Team for investigation.
I look forward to your response. Please note that if no response is received after two business days, the case will be closed and locked. After the case is locked, we will no longer be able to respond, even through Private Messages.
All the best,
