Can't access email
I have Cox Ultimate Internet, along with Ultimate TV with Contour and home phone service, but cannot access my email, nor even any of the "Internet Tools" on myaccount.cox.net. I only have 1 login ID, the primary account, and can login to cox.com just fine to pay my bill, view my services, etc., but when trying to access "Internet Tools" and related features, it shows "You are managing email address: null@" and acts like I need to sign up for service. I've tried logging out and back in, clearing cookies/temp files, multiple browsers on different computers, all to no avail. I can't access email, can't download McAffee, can't run the speedtest, can't check data usage, can't set up additional email accounts. There are several other issues too, but I don't know that this is the appropriate forum for them... caller ID on TV does not show up, cannot pause/rewind TV, DVR jumps around when using fast forward/rewind during playback(jumps 10-20 minutes with the first press), TV pixelates/tiles, can't reset cable boxes with the online reset tool, can't access/manage phone messages online. I'm sure there's more, but that's just off the top of my head.
I've tried emailing support with no response, any suggestions on what I can do to fix this?
