Locked out and need to changed username

I need to access our account and seems we have been locked out. I also need to change the username or add more users to the account

We would like to apologize for any inconvenience. I have checked the email address you are contacting us from and it is not linked to any JotForm account. May we ask that you provide us the username of your account and/or the email address your account is linked to, please? You may also provide us the link to any forms in your account that we may use to search for your account.

We will wait for your response.
