They are not going to work with you. I tried.
For me, it was also Cox but they were saying it was for not returning the box which I actually had to pay for. But it was so old, I had no way to prove..... And the box was long gone.
But trying to get a house so I had no choice but to pay.
So, I had them send me the agreement to delete in writing. They sent it to my email and once I got it, I paid the account.
I'm not sure if you noticed but this thread is almost 3 years old.
