This just happened to me too!
Another users post below. It just happened to me too, I have never in my life been charged for a declined credit card, which number changed due to fraud. The customer reps (escalated to manager) were nice but absolutely refused to help. This is crazy. Absolute fraud in my opinion. And COX do your employees a favor and please empower these decent people to be able to help and provide a refund for such a bizarre charge.
"I was just charged $25 by COX due to a declined credit card. I've never experienced this before from any company. I use this card regularly without issues, and have since used it without problems. I am unable to determine the reason it failed in this case. It is currently a valid credit card? Furthermore, there are various legitimate reasons for a credit card to be temporarily declined, especially given the prevalence of online cc security issues. As long as the issue is rectified and the bill is not overdue, there should not be a charge. This is not equitant to an overdraft on a bank check. This is ridiculous! "
