When is the best time to dispute with the cra's in December? Early, so the 30 days expires around Jan 1st, or later, say the 15th so the most likely time for creditors to respond coincides with the holidays?
I have never heard of timing it for the holidays, but now that you mention it, you never know if it might work. but 30 days is a long time to respond even with the holidays, I think if they are going to, they are going to.
