Owe? Or does it just show that you got the tab and how much you paid off with your first bill. It's hard to tell what's going on without seeing your bill. If you want to take a screen shot (minus your personal info) people can help you figure out here.
I can assure you the charge for the phone will not appear on the bill unless you cancelled service which is not the case here. As Chris suggested, if you can provide a screen shot of the Account Detal section of the bill, that would help us immensely.
