Rude and unhelpful call centre agent hung up on me

I recently completed an application for "price lock". According to the website "Your documentation has been approved and your order is on its way to you. Order number ********** 497" . After almost a month of not hearing anything, I called the call centre to enquire and was told that they can't see anything on their system and they would have to send an email. I've already had an email sent last week with no feedback. The call centre agent then put the phone down in my ear. She had my profile open and could have callled me back if it was an accident.
