"As Verizon has been paid for going on 3 years the full amount that was owed, there is no more incentive to continue reporting the Charge Off on my records "

But there is. It's part of your credit history and is being reported acurately from what you say. The whole point of a credit history is that it shows just that, your history. If we could have everything bad removed once we paid it, there would be no point in having credit scores.
