US Bank 's XXXX XXXX Credit Card had as their featured benefit, a second award night free as their main marketing tool. After paying the XXXX Annual Fee they suddenly cancelled that benefit effective XXXX/XXXX/15. How can they collect an Annual Fee and then change the main benefit, US Bank thinks they can change the rules after the fact. When I called in and complained, they said there was nothing they could do about it.
