Hi sidneycyster,
Your bill should provide a clear reason why it is higher than you expect.
If there are account charges, fees such as a late payment fee or others, they would be itemised.
If you still need assistance working it out, we don't have access to or visibility of customer accounts here on our forum.
Please contact Optus directly. And feel free to come back and let us know what it was.
