[substeps] Tell the representative that you are a victim of identity theft, and ask to have your accounts closed or frozen. 
If there are any suspicious or fraudulent transactions on your account, you can dispute them as well. Make this call as soon as possible after you discover that you've been a victim of identity theft-don't just wait and see if any unauthorized charges are made.
