I am having this exact same problem.  Their support ticket system is very slow as well.  I have tracking data that assures me my money order we received over a week ago and the website says that money orders are processed within 1-2 business days.  It also states that handwriting can slow down the process if it is poorly written.

I wrote everything as clear as day so there should be absolutely no problem reading this.  The only thing this leaves is a lack of workers... it seems they are getting to big for their current staff and should expand, or increase productivity somehow.

I have nothing left to do but wait, I am sure they are very busy.  It seems they were updating their server (?) recently if I remember reading correctly which could slow down all processes if their staff is managing many different tasks at once (transfers, maintenance, etc)

I sure would like a response though.. even a simple "ok, we received it and it is being processed but we are delayed currently because of x, y and z."

oh well *twiddles thumbs*
