JPMorgan Chase & Co. Bank Account Or Service Complaint

JPMorgan Chase & Co. Bank account or service department,

Checking account Account opening, closing, or management Texas

On - I received a letter from Chase Bank stating that 'after a recent review of your account, we have decided to end our relationship with you. ' Account to be closed on - -. I have been with Chase for 8 years. Never any overdrafts. Paid off a mortgage thru them and paid off a new vehicle loan. No one can tell me why or what triggered them to close my account. I want a specific reason, not just 'due to a review '. I need to know what they saw on this 'review ' to make this decision.
