Can't verify my comcast.net email address. Confirmation email not being received.

Trying to setup an account with a music forum but I am unable to complete the signup process because I am unable to verify my comcast.net email address.  I cannot do this because I am not receiving the confirmation email in my inbox or in spam folder.  I have called and am very disappointed in the level of support being offered. Seriously, only the most elementary issues are being handled through the 1-800 support number.  I was told to wait 24 hours for a higher level of care which was that in name only because the agent had very limited knowledge or access to anything proprietary. and that failed.  Now I on a 72-hour wait to speak to what I guess is the super duper extra level of Comcast care and it sure better be just that because if I have to wait 4 full days to address this silliness, I think it's time to rethink who my internet carrier is... lol
