When Consolidating bills with credit cards that are "written off", what happens?

Written-off means that the company is writing off the debt in there books for tax purposes (so they aren't showing your debt as income). They do that when they don't believe that they are going to collect that money. They will still try to collect and you can still pay it off to show paid on your credit report. A write off is worse than a delinquent account. I hope this info helps. Good luck
