I find it interesting that all of the 1-star reviews over several sites make the same grammatical errors. It seems as though one vindictive person is making multiple accounts to trash DCU. My experience with them is brief, and their rewards are on the modest side, but I haven't had a problem with customer service. You might take the 1-star reviews that have been posted to several sites with a grain of salt.
