Can't get my phone number accepted will not accept
Randy, most likely the rep who activated your account already set you up with Self-Serve (that's why it won't accept your phone number a "second" time). They asked you for an email address at activation, use that same email address and try to log in. It may just work! It did for me when I joined, I never had to actually "create" my Self-Serve account, the rep did it before I even knew it existed. Try it!
