oh, man the child tax credit office make such a mess of things. We've had ours stopped, been told we owe them, been told they owe us, it seems to change with every person we talk to. If you do owe them they take it out of future payments. Don't know what to tell you, but good luck trying to sort it out. I guess I'd send in the thing for an appeal, and have you tried talking to them. There is a chance it's a mistake. Wouldn't be the first time.
