JPMorgan Chase Credit Card Complaint

JPMorgan Chase Credit card department,

Closing/Cancelling account California

I have a long lasting relationship ( When Wamu was bought by Chase ) with Chase, however, out of the blue, all of my credit cards were closed by them. I called them to try to find out why and they did n't give me an answer but a very generic unexpected activity ''. That does n't tell me anything as to why all - of my credit cards were closed simultaneously.
