Can't login. an e-mail of mine.

Tony John:
I filled a form in, to Login By Verifying who I was.
I use free computers. I was at the Tech. college,
though. The phone is the same one I used when
opening the account, but, they would not text
me a CODE. So, the single use code was not available.
I filled in as many details as I thought would verify
that I was who was trying to get in this account. They
mailed me that they had blocked my account, that I failed
to prove who I was. I'm sure they may close this account.
But, because I was at the school, I thought the security
problems were, secure. They didn't use phone verification,
or text me a code, so what can I do. The e-mail to contact
me on is:
Arthur Dupont.
