Account charging not working - but apparently it is - duh!

According to my tickets my usage has just been reset - fine except I have had no notification of the charges and no transactions showing.
Now I am very happy to have got a free month but I bet Plusnet aren't

Hi Jim,

An invoice has been raised on your account for £xx.xx. This payment will now be processed by your bank/building society.

I suspect that you will have received that m,essage 19 minutes after making your post.

Being a trusting soul  I will accept that it was the automatic system without a kick from James

If it was me, I would have posted at 10:20
Billing doesn't happen at the same time as the usage resets, and as far as I'm concerned, it never has.
They're two separate activities that happen on your billing date.
