Comcast email accounts hacked

Had multiple issues with Comcast emails accounts. Locked out and unable to login and/or change password. Endless loop of no help.

 Finally deleted accounts on PC and rebuilt each account. Now getting daily spam, phishing emails directed at only Comcast email accounts. Have Comcast email servers been compromised??? Very, very poor customer service including forum postings that cannot be replied to, no compensation for hours and hours of attempting to reestablish these accounts with little or no customer service.
