You don't need to make two threads man ^^ But back to the issue, how someone got your account is a mystery (the only thing I can think is that they looked over your shoulder whilst you were checking the old account [or the new one also, if they have the same password]).
If they do have the same password, change it ASAP.
The best thing you can do is report this WLM... they should be able to help.
