Are the messages in your webmail Spam folder? If not, check your Spam settings. Make sure that "Enable spam filtering" and "Save a copy of emails marked as spam" are both selected (see https://www.xfinity.com/support/articles/spam-filters-and-email-blocking-new-experience).
If the settings are correct and @CCAntiSpam or another employee doesn't reply to your message here, Comcast Security Assurance should be able to help.

Don't know if problem was resolved by Comcast but I added the email address to my address book ( email address provided by another email from a different section of the company I was trying to get the password reset from), and when I tried the reset password option from the website I was trying to access, the email get right through. Thanks for the help
Same problem occurred the past few days. Tried to reset password, form said password was sent, email from the company said password was sent but no email in my in box with the link to reset my password. This is an ongoing problem with this particular email address. Why can't it stay fixed? The email is still in my address folder as an address I want to receive emails from
