Last night I got an email from Kogan:
"Thank you for your recent order with Kogan Mobile.
In the first two months since Kogan Mobile launched, some customers did not receive First Class Service and we would like to apologise. We know that you experienced a porting delay, which may have been very frustrating for you. You may also have had some difficulty contacting our customer service team, while large numbers of people were seeking updates to their porting issues at the same time.
Whilst the porting delays were entirely out of our control, and arose as a result of issues faced by Telstra Wholesale in establishing its new prepaid mobile platform, it nonetheless remains unacceptable for any Kogan customer to have this sort of experience.
Since the launch of Kogan Mobile, tens of thousands of customers have left their existing providers and switched to our new service. Our customer service team has grown by over 500% and we have made many improvements to our systems and processes in order to ensure First Class Service is provided to all our customers. Meanwhile, the network operator continues to work hard to resolve the underlying issues:

Whilst it is only a small proportion of customers who have experienced issues, we are deeply sorry to those who have been affected and we would like to offer you a $25 gift voucher which you can use on anything in the Kogan.com store*. We would also like to offer you a further $25 gift voucher that you can share with a friend who wants to make their first purchase from Kogan.com"
tl;dr After them having issues with porting numbers from Telstra they've given people 2x $25 gift cards to use on their site. You can use both of them (in separate purchases only), you don't have to give the other to a friend.
lol i never would have seen that coming
