Getting a message that says "quota is filled"

how do I fix this?  I have people filling out the forms but are getting the message "quota is filled".  How do I fix this? 

Hello @cpalmiere, I'm seeing you have now upgraded your plan to Bronze. The limit you reached while you were on the Free Plan was the 10 payments / month limit.

But just to be sure, I still cloned your form and did a test submission and it is working as intended. If you're still having issues though, let us know so we can have another look.
