Sorry for the trouble here, Dan! We're migrating to Cursor support systems, and your email fell through the cracks here. We're working on fixing that now.
I can see that Learn Lux was given the $1,500 start up credits, but you used those up after a couple months since your org started an annual plan and added additional seats.
You had 2 seats on an annual plan in February for $960 (covered by the credits), and now I can see you're up to 7 seats on your most recent invoice.
