Furthermore, there doesn't appear to be anywhere on-line on an Apple site where customers can complain about this (or any other) problem.
After more wasted time going round in circles on the "support" website, I found a page to submit a complaint (and also requesting a reply), only to be met with:
“Thank you for your feedback on iTunes.
We cannot respond to you personally, but please know that your message has been received and will be reviewed
by the iTunes Team. If we need to follow up with you on your ideas for improving iTunes, we will contact you directly.”
Does Apple think it is beyond reproach?
More wasted time phoning yet another operator finally (and somewhat reluctantly on their part) revealed an address that complaints can be addressed to:
Apple
Attention: Customer Relations Department
Customer Services Admin
Hollyhill Industrial Estate
Hollyhill
Cork
Ireland
For what its worth, my letter is on its way to them now, I suggest others do the same.
