Cisco wouldn't be the first nor the last to do that, with all gear if
you have to buy support to get patches and other software or firmware
updates, but to be fair to Cisco TAC they are normally very helpful and
put you in contact with the right person to help you out.

I have had a similar run-around with AT&T Broadband and Sprint a while
back, pertaining to a DoS attack my organization was experiencing. Not
to dive into details, to resolve the issue, I got them both on the line
in a 3-way conversation, and it was taken care of in less then 5
minutes.
They didn't seem to eager to shrug off the responsibility to someone
else, when that someone else was right there on the phone.
