Support request, please help! @XfinityCSAEmail

I have been having an impossible time dealing with Comcast/Xfinity support...

A week ago I created a ticket requesting to block port 25 on my modem/account, there were series of concerns that were addressed (i.e., port 25 is blocked by default due to spam, etc etc.) and I explained clearly that I have no intention of using the port for spam/emails.  Long story short, a week and 8 hours of call time later, port is still unblocked and NO BODY, NOT THE SALES TEAM, OR THE TECH DEPARTMENT OR THE CSA OR WHATEVER HAS BEEN ABLE TO HELP!?!?

I'm sorry but this is very frustrating as I'm running out of patience.  Please help @XfinityCSAEmail
