Did they told you that they will generate income on your blockchain wallet automatically? If yes then a pure scam since why the hell they will setup your account if you can setup your own. The next step after the account setup is to fund your wallet, I guessed.
As long as no money involved which you will deposit, you are safe. As long as no install browser plugins are required, you are safe. As long as you are not clicking any links from them, you are safe etc.
.. at least i did not lose much.
you mean you already lose a little?
