I have a comcast email address and they are a pain in the arse. When we moved 4 years ago Comcast was not offered at the new house so I no longer have an account with them. If I ever need tech support for email they are now impossible to contact. Also they no longer accept gmail email from anyone. No idea why but it has been like that for about two years now. They also have a major problem with blocking me from sending email 90% of the time. They claim there are too many incorrect attempts to log in or something. This is also a known problem for several years. If I didn't have business cards with my email address on them that I gave out over the last 30 years I would drop them ASAP.
