I got a response back from Wells Fargo Home Mortgage regarding my GW letter. Here's what they said:
This letter is in response to an inquiry for a credit adjustment. We have researched our records and determined that an adjustment is not warranted due tot he following reason(s):
The payment for the month/s of October 2004 and November 2004 was not received by the required due date.

So, I guess I should send another GW letter!
