Unable to access phone tools/settings on my account

Hi, I've returned to COX in July with TV internet and a phone line. I can access my account online, see all my services and pay my bill. When I click on phone tools or any of the phone settings such as voice mail settings, etc I get this message:

I have to COX Iphone app and I've been unable to access phone tools from that either. It's now been doing this since July and I'm wondering if it is an issue with my account. Who do I contact to check this? It would be convenient to be able to use the online phone settings/features which so far I have not been able to. 

Thank you
