Cox is perhaps the worst in the industry when it comes to billing. I signed up for cable/internet/phone services. After 3 weeks of problems with the cable, I get a disconnect notice in the mail for non-payment (really, it was 3 weeks). I called and was told that they had sent a bill (which I had not received) so I paid over the phone. The same thing happened the following month. And the 3rd month. When I spoke to customer service I was told that they were sending the bill via email, but the rep could not give me the email address that the bill was being sent to as it was confidential. The fourth month I cancelled the service.
