I have had a Citi Forward card since XX/XX/2011 and the rewards offered were XXXX Thank You points per dollar spent in restaurants and entertainment. This week I received a letter informing me of the forced migration in XX/XX/XXXX to a new reward scheme offering just XXXX Thank You points per dollar spent in the same categories, devaluating my rewards by XXXX %. Over time the monetary value lost in rewards may be higher than {$500.00}. 

I have called Citi requesting to stay under my current terms or migrate to another card with a similar or better value proposition, but I was not given any option.
