I can imagine how frustrating this must be right now. I really hope the timing of all this works out and your ANC rebounds enough for you to continue treatment.
I am not sure what you can do since you are right. It is the weekend and on most of the guidelines it does indicate to discontinue PegIFN until resolution when ANC < 0.50.
It's as flcyclist said in his post as well as in this chart
