How can I make a phone call w/o them knowing who called or even my #..?

If the *67 doesn’t work, here’s one surefire way to do it.
Go to the Dollar Tree and buy one of their calling cards. They are one dollar for 35 minutes, and can be used for long distance, too. Dial their toll-free access number, then the PIN for that card. Then enter the number you’re trying to call anonymously- untraceable.
