Credit Protection Association LP Wrong fully Turned Into 3 Major Credit Bureaus Dallas Texas

I worked in New Orleans Louisiana for about a year and had cable with Cox Communications. I payed my bill in full when I recieved the final statement and one week later I recieved a letter from Credit Protection stating that Coc had turned my account over to them. I contacted Cox to see if they could explain this and they stated that they had never turned it in and that they would take care of the issue. Two months later I recieved another letter from Credit Association stating that they were going to turn this in to the credit bureaus if I didn't pay the bill. I contacted them again and gave them the reference number that Cox had given me and told them once again that Cox said they had not turned this account over to them and so I asked them how they recieved it and there response was we can't give you that information and that they would not contact Cox, Cox would have to contact them. Now here it is three months later and they turned me into all 3 of the major bureaus so I contacted Cox again and they filed another report and said it would take up to ten days to get it straightened out. Isn't this illegal to ruin a persons credit when they have done nothing wrong? I believe that this would fall under the catagory of defermation of character does'nt it. I would apprectiate any help in trying to resolve this issue. It's a shame when someone goes to a place and volenteers to help in a major catastrafee and then has to deal with something like this. Thank You for your time.
