Cannot create email accounts

This has actually been going on for about a year now. I have also had help from tier 1 support, who hasn't been able to solve it either. It is now in the tier 2 queue. 

Basically, I cannot create working comcastbiz emails. I first noticed it when I couldn't access wifi (I have xfinity home also) and was told I should be able to use wifi by signing in with the convoluted Comcast business email address. Whenever I try to create one, it either doesn't work (no password works), or it just wont finish creating it (the most recent issue). I'm stuck at "Review email box information". Pressing "Submit" does nothing at all. i also get locked out of the website and have to reset my regular password when this happens. Im sitting here waiting for tier 2 support to get around to helping me. I think it's ridiculous that this problem has existed so long and nobody has placed any attention to it. I seriously think it's a website problem, not a system mafunction.
