Washington Mutual - JP Morgan Chase after switch they increased my intrest and then closed my account miami, Florida

I was holding a WAMU credit card, and i always paid more then twice the minimum, and i had never been delinquent.  When chase took over about a month later they increased my intrest rate from 9.99% to 21.24%, when i called and asked why they were rude and never told me why before they hung up.  Then a week or two later they closed my account and said the only way out was to pay entire card off.  I completely disagree with how they took over good customers and just basically steal from them with no regard to the people who bailed them out when they screwed up.
