Welcome to the community
I was able to locate your account using your community details. I've seen that last 23rd of November you made a outgoing call on a Mobile cost $16.90.
Our system sent automated e-mail to notify you that your balance, when your Prepayment becomes low, we attempt to debit your nominated payment details for a top up.
At the moment I can see that there is enough current prepayment balance. Let me know should you require further assistance.
Thanks for sending us your details. I arranged one of our Account Specialists to call you tomorrow between 9-10AM AWST to discuss details about your account.
Let me know how it will go and should you require further assistance.
