Bug on the official website – Refund problem

I need help and I can’t get it.
I bought the plugin a few days ago and I can’t activate it. I bought it just as they were doing a site transaction (themeum for tutorlms).

I can’t find my activation key on the new site.
I’m wasting time with this setback.

I would like a refund.
My paddle order number: 61935096
Date of purchase: May 24, 2024
Amount paid: US$ 159.20

I’m waiting to hear back with my refund.
