I am trying to cancel my club carlson visa card and got this message from US Bank "We understand that you would like to close your Club CarlsonSM Premier Rewards Visa® Signature Card account. Before doing so, we would like to advise you that closing your account would result in the loss of earned reward points." Is that possible? Once the points are deposited in the Carlson account, surely US Bank cannot take them out? Note that I've had the card for a couple of years.
