Remove Weebly Site

[Canadian2]

I have a weebly site created many years ago as part of a highschool class. Now as a young professional the website is interfering with the search results for my name, and when you look me up one of the first things that appear is this website with very old assignments posted to it. 

Unfortunately, I no longer have access to the email address used to create the account, and don't remember the account login info. I attempted to call weebly support to address the issue and verify myself, however they require a support number to call through. 

How can I have this website taken down?

Thanks!
