unable to get online or call cust svs on phone

After researching my problems listed below, I believe there might be a restriction on my account. If so how do I know if that is the case?

If not, this is what is going on:

I am having issues with both calling customer service and logging into any cox site that starts with "m.". The phone system won't take any type of payment. It just throws me back into the loop. The online will not load any site that starts with the "m.".

What could be causing it and what can I do as far as paying if I can't use either option?

Thank you in advance for any help.
