Did they eventually take them away? Mine got taken away on my last statement and I received a letter stating that the earn rate was 1.0 per dollar.
But they had been clearly marked as "Bonus Points" every statement and they had been giving me them for probably about 6 months.
It seems a bit like your boss saying "we gave you Christmas bonuses for the past 5 years but now we find them not in accordance with policy, so we are asking for you to repay them back"!!!!!!!!
I got them for about 6 months, and while they stopped paying in May, at my July statement they had not reversed any out. Maybe in time they will....
