web mail defective - Time Warner Internet

This question is about "web mail defective", with Time Warner Cable internet and apps. Anyone know why with the web mail interface it appears I have many pages of messages, but clicking on the "next' or any of the numbers (of pages) nothing happens. Same thing happens with chrome and safari. (mac)

Ridiculous that the web mail is not only slow, but next to impossible to access, and then when I do I can't get to messages beyond one screen. It was the incompetent tech support who told me to use web mail, since they don't provide support for outside programs, but even that is defective. Any advice here?

web mail defective?
