JPMorgan Chase & Co. Credit Card Complaint

JPMorgan Chase & Co. Credit card department,

Closing/Cancelling account Texas

On or about -/-/-, I had my Chase Credit cards canceled without warning or notification. Upon calling to determine the reason I was told a letter would be sent explaining why and that no one would be able to inform me over the phone why my cards were closed. When I received said letter, it only informed me that my money market, savings, business account, and credit cards would be cancelled. No explanation given whatsoever, I have attempted to request at a local branch, but again no information is given. I am confused as I have all my accounts in good standing, do not engage in illegal activity, my payments are made on time and my credit score ( is/was ) above -. I am more upset that despite my good standing a card can be cancelled without warning, this would have been extremely dangerous were I traveling abroad or in some medical emergency.
