Trying to Delete CODM Accounts

I have been trying to delete multiple CODM accounts for about an hour with no luck. It looks like, in the past, there was a button in the game to start that process but no longer. They send you to Activision's "support" page and you have to go through a process to delete your information. The problem is, even after entering my account information, the option to submit is greyed out. Is there any real-time support from Activision such as a proper chat feature or phone number?
