Hi CallCIA,
Your best option is to contact EA Help so that they can change the email back to yours. If you use the Contact Us button at the end of the guide below, you should be able to initiate the process. However, keep in mind that they will need to confirm ownership and will ask you security questions, so it's a good idea to have as much information about the account available to you as possible.

After the email address has been corrected, EA Help should be able to initiate the appeal process to find out if the ban can be revoked.
