As we don't have visibility of customer orders here it would be best if you checked with Optus directly.
I'm afraid we don't have access to customer accounts here on our public forum, you'll need to contact Optus directly.
So I became an Optus customer today and ordered an iPad Air on a plan. According to the Optus website, these are in stock and available for delivery in 3-5 business days.
However my confirmation email, sent a few minutes later, directed me to the Raincheck and Backorder Process page.
This sort of outright dishonesty and misrepresentation regarding the availability of hardware is unethical at best and is not a good start for what’s to be a three year relationship with Optus.
It’s 2020 Optus and there is no excuse for not keeping your product availability up to date on your website.
I note that your website still says the iPads are in stock, no mention of delays, backorders etc. and still promising delivery in 3-5 business days.
What’s going on and when can I expect my iPad?
