No Longer Able to Get Back to Account and/or Setting Page for Website

I believe I am in the most current version of wordpress. My account was set up in Dec 2010.

I was in WordPress editing my website. I was on the Settings page editing the title of my website. I accidentally changed the original url of the website which had all of the designs to the new website url (I can’t remember exactly what box – forgive me I’m new at this) and now I am unable to get back to settings or even into my WordPress account. Any help and/or does wordpress have a customer support via telephone?

Link to present website: https://www.payless4hcgdiet.com/wp-admin

The system is not recognizing any of my emails at this time and I’m sure it’s because I did not set up the account with the new website address.

thank you.
