I have been trying to access my old twitter account for 2 years, trying to reset my password but never receiving the confirmation email. I tried contacting support multiple times, providing plenty evidence that I am the account owner, but I get ignored as they say "your email doesn't match the email associated with the account". After 2 years I remembered my password and logged in. Guess what? The email linked with the account is the email I've said it was the entire time. Thanks for nothing.
