I've been on Prepay Carry Over 19 since it launched and had built up a nice buffer of call minutes and data.
I also had a monthly auto top-up of $20 each month so I thought I was safe from losing my carry over.
Clearly my own fault that I missed that the fact the the Prepay renews every 30 days whereas the auto top-up happens on the same day every month and I've become so used to getting bombarded with renewal texts that I missed the fact that this month my renewal happened on the 4th but my top-up happened on the 5th so I lost the carry over.
Sadly I was only one top-up away from extra $1 each month being able to cover the renewal.
Is there any way I can set my top-up cycle so is matches my Prepay renewal cycle so I don't have this problem again?
