Milesource as far as I can tell from my own experiences is a scam. Earlier this year when I first joined them they rarely credited my points correctly. In response to my e-mails I just got the runaround. Finally, after calling & leaving several message, plus being told by a customer service rep she would call me back. She never did! I have given up!! I thought about reporting them to the better business bureau, but unfortunately as they probably count on I have little time to pursue this matter.
