My account was suddenly closed. When I called to find out the reason I was told that the recent activity on my card was the reason for closing the account. The only activity that had been done on the account in the past two months was paying off the total balance and then using the card and paying it off in order to accrue more fun points. Upon the closing of my account all of the points I had accrued over the three years of having the card were forfeited as per their policy. I suppose not sitting on a large balance and making small payments for eternity is a threat to their business.
