Yup, I went big with this promo. Many miles posted (though a fraction of the miles I'm owed), some retracted. All my accounts (7 or so, all in my own name with real info, no obfuscation or trickery) cancelled without notice. When I asked why (when I couldn't log on), I was told due to "fraud". Except they never explained what I had done that was fraudulent.
FreeCause is stonewalling now (they were quite helpful at first), so U.S. Dividend Miles needs to step up and protect the integrity of their mall. T&C were explicit "No Restrictions" and "4757 miles/online purchase".
