Using an AI agent and offered 400 credits as a reward - not credited

I was offered 400 credits if i used an AI agent to help code, so i used claude and when coding it ate up like 100 of my credits almost. It then did not credit my account. I would have used gemini outside of netlify if i had known this would happen, as i now have less than half my credits left and it is day 3 of the month. I thought i had followed this promotion exactly, if not the instructions appear not to have been clear and may mean i cant contiue to experiment with your platform this month. A bit disappointed.
