webmail attached to account wrong - Time Warner Internet

This question is about "webmail attached to account wrong", with Time Warner Cable internet and apps. Hello. My problem is that the webmail address attached to my account isn't correct. At one time the account was in my uncle's name. We had everything changed over to my name. I recently tried to download the security suite that spectrum provides but I can't due to webmail. The account still lists the webmail address that was under my uncle's name (despite everything else being linked to my email account). I can't even sign in to manage the webmail accounts since it wasn't my account to start with. I just want to be able to download the spectrum security suite for my computer.
