My ONLY e-rewards account just closed with $250 balance, even after sending in the complaint. No read reason given (just some .... about one account per member allowed and similar). My sin - in my opinion: had done over $300 per month regularly and always redeemed $100 for United, Iberia, British and Avios, netting 2000 United and 5000 Avios miles every month. As I don't have any other e-rewards accounts, I obviously couldn't earn and redeem from other accounts. Obviously, this was too much and too expensive for those pigs. Thinking of suing them in front of small claims court. This is just unacceptable business in my opinion. So, all that still have active accounts: do no hold any balance, spend all that you can. You never know.
