Can you call them and ask that they report?
I had financed furniture and to help my credit out, I asked them if they would report it. They said they usually wouldn't report payments, but since I asked them to, they were nice enough to do so.
Since they are charge cards, I don't see why they would have a problem to report. They pulled your credit when you applied for them so it only seems fair they should report your timely payments. I know they would waste no time if you were late just once. Funny how they are like that.
