voicemail commands

Has anyone else noticed that many of the Voicemail commands don't work any longer? When I am listening to a message, 7-7 still stop and deletes, and # will skip the message completely, but I can no longer skip forward (3), skip to the end (3-3), skip backwards (1), start over (1-1). That means to save a message (9 still works after listening), I have to listen to the whole message since I can't skip forward. I don't use Comcast VM as much as I used to (since I have other numbers now too), but it's still a pain to listen to VM when the commands no longer work.
