Product: Credit card or prepaid card

I apologize for the wall of text ; my paragraphs do no seem to show up. 

My XXXX credit card sent me some of those promotional checks with 0 % interest for X months with a 1 % fee. A month after it expired I messaged customer service and asked if they were running any promos like that. I was told that check would still be good to use and so I did. Now they are charging me interest and saying because it was cashed a month after the promo they can charge interest and they also charged a 3 % balance transfer fee instead of the 1 % What are my options here? I have what they said all in writing on my cc 's messaging system.
