Account info and bill pay - DirecTV

Because AT&T did not service my area, I only have DirecTV. So my question is; is that possibly the reason I cannot bring up my account online? I want to set up auto bill pay, but, website gives unusable directions, or, keeps reverting back to intro page. What can I do, on my end, to log into my account?

This question, "Account info and bill pay," is about DirecTV channels, programming, equipment, and sports.
