Comcast blocking G Suite Domain - Who to contact

I am trying to find out who to contact regarding an issue that I started having yesterday. My emails from my google apps domain, are not being delivered to addresses, including my own. They are just vanishing into thin air. The emails are showing as delivered on G Suite and are being delivered to everyone in the world except addreses.


I tried calling the Comcast Security Assurance number as recommended on other posts here, but they told me that "Comcast does not block any email", which is obviously false since they have a blacklist. They kept asking me to go in and just check my email and insisting that the issue is with Google's servers.


Any suggestions that someone could give on who to contact regarding this issue would be greatly appreciated.

Comcast has a blacklist.  Here's how to get your mail server off of it.

Get the IP Address of your 'sending' mail server (SMTP), and submit a block removal request here:
