Yup. Override the email and give them a call directly.
Judging by past experience, don't pay attention to that ship date as they really don't ship on that date. The email you received is automated so it wasn't sent by someone sealing your envelope.
Any problems or even IF you ever lose your tickets, TeleCharge simply cancels the 'lost' tickets (so the barcodes don't work anymore in case someone stole them and tries to use them -- they won't be able to), and they reprint a new set for you to pick-up at WILL CALL at the theatre's box office.
Also, if EVER you leave home without your tickets AND you purchased them thru TeleCharge... no problem. Just call them up while you're outside the theatre, and they'll call the box office directly and reissue your forgotten tickets. Yup, even if you don't have the confirmation number -- they look up your order via your name. If you have the credit card number with you... even quicker for them.
I'm still baffled when people panic about these little scenarios when a simple use of common sense provides you with ALL the solutions/answers.
