AIB credit card, direct debit before statement received

I currently have a AIB business credit card which according to their T&Cs must be paid in full by DD each month.

This morning I checked my online banking and saw a DD for 2.5k gone out for the card payment but I had not received any statement advising me of how much I owed. I was forunate that there was just enough in to cover it. But if there was not enough funds I would be facing bank charges and unauthourised OD fees etc.

Is this practice of DD before a statement acceptable?

Edit: Postman has just handed me my statment dated 3rd of October! The statement balance matches the DD. I still think that this is bad form from AIB.

Why do you think that AIB are culpable for the seemingly delayed post?

Only allowing 6 days for the DD (and not allowing for their internal mailing system and an post delivery) is a bit over zealous of AIB imho. Also they never post statements on the date they are printed. Same applies to most utility companies.

My MBNA statment is always dated the 15th of the month, I never receive it before the 20th. So the problem is not endemic to AIB.

BTW, what sort of CC demands full payment by DD each month?
