Just bought an account from vbarrack.com, advice for being extra secure?

[Pelican]

I have all the info except for the last name of the original account owner. I changed the e-mail for the account twice so that the previous owner would not be able to recover it since they had seen the first e-mail I transferred it to. Anything else I can do to be safer?

sorry buddy, without the last name you can do everything you want to secure it, but ultimately, the original owner can recall it if he wants to put in the effort

Actually I just got the last name from their live chat...hopefully they didn't lie about it.
