I don't have access to a form I've created after downgrading my account

I upgraded to a bronze account. We are having trouble access on a form we created. It says that we aren't the form owner. We are desperate need of this form. Can you please help me?

Thank you for contacting us.

Could you please share the form's URL with us, so we can certainly have a look and see what's the problem?

Thank you, looking forward to your reply.
