my email inbox disappeared

i've been through every trouble shooting possibility more than once. at this point i am quite sure something is wrong on the comcast backend

@user_128ef4, I understand how important emails are to our everyday lives with just about every service you can imagine requiring one. VPNs are great for protection, but they can also interrupt your ability to connect to many services. I know you have tried many things, but I just want to make sure we are covering all of our bases. Are you using a VPN by chance?

Our Customer Security Assurance (CSA) team actually handles much of our comcast.net email inquiries and issues. We often work directly with this team, but you can reach them directly at 1-888-565-4329 between the hours of 8:00am - 12:00am EST, 7 days a week. You can also visit their website to submit a ticket at https://spa.xfinity.com/report, and they will gladly assist with an advanced issue like this. If you decide to go this route, please keep us updated on any new findings.

that is who i've spent hours with on the phone... and who continues to not call me back

i have tried everything they have asked me to, including checking vpns, incognito, different browsers and devices... no problems have been resolved, and given the lack of call back, it doesn't seem like its not being worked on

@user_128ef4 , thank you for letting me know of your experience, and the troubleshooting steps you have taken. I can definitely work to find a solution, if you could please send our team a direct message with your full name, the name listed on the account (if different), and the service address associated with your account.

To send a "Direct Message" to Xfinity Support: 
Click "Sign In" if necessary 
Click the "Direct Messaging" icon  
Click the "New message" (pencil and paper) icon 
The "To:" line prompts you to "Type the name of a person". Instead, type "Xfinity Support" there 
- As you are typing a drop-down list appears. Select "Xfinity Support" from that list

Type your message in the text area near the bottom of the window 
Press Enter to send it.

@Again​ I've asked CSA and some operations folks to take a look.  The mailbox may need some maintenance, but they'll have to look.
