Who I have the same questioned this topic

After I sent a code to donate, I get a message asking what my billing zip code is. I reply with that and get a response saying, "Your wireless account is not eligible to donate. Your donation cannot be processed. You can still donate at redcross.org. Terms at mGive.org/T." Does anyone else have this problem? I have a prepaid plan and thought it was supposed to be deducted from my prepaid balance.
