Didn't receive confirmation email

I ordered a new phone on June 16th.  My tab balance has changed and in self serve it says that I have ordered the phone.  I never received an email with a confirmation so I cant track the order.  I did check junk.  When I try to use the chat it asks if I received the email, I say no, it says if your order went through you will have received an email, check your junk.  If I try to respond to that message it acts like it is a new question assuming that for sure answered my problem.
