XBT, Pjiang, and other experts, please help one question

I sent a letter to NSC to withdraw my NIW 140 last week. But, I check my case and yet not see any change for my case online. It looks that nobody open my letter and then updated my case. Is there any good way to get this doen?
Happy a lunar new year of 2008!
