[400] Billing hard limit has been reached "But that's not true"

I just signed up with OpenAI two days ago and tried to run my first scenario using MAKE.com website and this error message popped up and I just got started. How did I use up my limits so fast with my very first scenario run? I had a FREE account and upgraded just yesterday thinking that would solve my issue. But, I still received another error telling me the same thing about the billing. Can someone please help me resolve this issue so I can get back on track.
