Boa noite não atingir os parâmetro da conta grátis, porem meu formulário esta bloqueado exigindo upgrade, aguardo resposta 

We are sorry for the inconvenience this may have caused. I checked your account and it's in good standing, your form also works as expected on my end.

ok voltou a funcionar, gostaria de saber como evitar esse tipo de erro ?
