I signed up for the flybuys Optus Ultra offer in late June. I've just received my first bill however it didn't include the discount associated with the offer. I've tried contacting 13 39 37 however they were unable to help.
My original sign up confirmation email from firstname.lastname@example.org in June had the correct monthly billing amount.
Optus are well known for applying discounts included in a contract from your SECOND bill. Normally it's in the fine print but that's not that helpful.
I'd say there's a good chance that's the case for you to though. Maybe try live chat and ask them? - http://yesopt.us/chat2us
Follow @sam Sam's advice and give Live Chat a shot.
If they're unable to assist, we can always go in and apply the discount from our end.
