My Comcast e-mail accounts ( [Edited: "Personal Information"] & [Edited: "Personal Information"]) are totally screwed - e-mails lost/not working

In mid-March 2021 Comcast allowed my [Edited: "Personal Information"] to be hacked.  I lost years worth of important e-mails & it does not work any more.  I worked hours with Xfinity chat & in person with no luck.  In early April my [Edited: "Personal Information"] account suffered the same fate.  Can Xfinity completely restore these accounts & provide full security?  I'd prefer to stay with Xfinity with my bundle.  HELP!
