after 7.2 i can no longer login to my account

i have had my account since season 4 and after 7.2 i cant login...its a super old account and i forgot my email that i used so i cant even check my ticket on the website and im almost positive that a bot is responding to my emails lol they ask a bunch of questions i answer the questions and they just keep resending the same message with the questions to my email when i email support
