form over quota error when submitting the form

They are getting a message that the quota has been met? But I don’t know what that means or how to fix it. Please help!!!

We are sorry for the inconvenience this may have caused. I have checked your account and it seems you have reached your Payment submission Limit for the month.

That is why your clients are experiencing form over quota when they submit your form.

For more information regarding your monthly payment limit, you can check this guide:Understanding-Your-Account-Usage-and-Limits

If you want to increase your Payment limit, you may need to upgrade to a higher subscription.

Here is our available plans:

Hope this information helps.

Thank you.
