Let's ask the blockchain.

According to the blockchain, your account was created by the steemit.com faucet (aka @steem). Most user accounts are created by @steem.

The Wallet tab of your account is empty, except for 3.079 STEEM Power.

There's no record of any such payment anywhere in your account activity. Can you give some more details about this $9 payment -- what webpage instructed you to pay $9, and how did you actually make the payment (Steem, bitcoins, credit card, etc.)?

You can email contact at sign steemit.com if you don't want to discuss this publicly.
