No notification of product change?

[#1]

I recently downgraded my product from the "Pro" to the "Extra" (Half the price! Job's a good 'un!)
I must admit that I expected an email or something to confirm what I had done, but only after a bit of searching did I find in "Closed Questions" in the help assistant:
"Broadband product change scheduled successfully"
So I guess I'm all good to go at the next billing date and I don't need to do anything else but lie back in my saved fortune? 😄
But really.. an email or somoething would have been nice..

Cheers for the suggestion, I'd agree that an email would be a good idea, as per the details on the closed question:  124361713 the change is scheduled for the next billing date.
