I'm glad I use my own domains as emails now.

I had a Gmail account that I got locked out of (Had two-step verification, but didn't have access to my old phone number to be able to log in) and I contacted Google Support, filled out the questions, and apparently I didn't provide enough information to prove it was me...

Even though my IPs matched up, I was on the same computer I usually logged in as, etc.
Not to mention, how am I supposed to remember the exact month I registered my account? That was almost 4 years ago.

AND, how am I supposed to remember the exact day/month I logged into the account?

They should really make a different way to recover accounts.
They're easy enough to hijack, but when you need to recover, it's hard to get back.
