JPMorgan Chase Bank Account Or Service Complaint

JPMorgan Chase Bank account or service department,

Checking account Account opening, closing, or management Illinois

I have had a bank account at Chase for about 7 or 8 years. I have filed a number of claims regarding double payments to - with the Debit Card and a Credit Card. The merchant - has been refunding the amounts as expected, it seems more from my efforts than those of Chase. I was told on or about - -, 2015, that the Claims Department was going to close the account without explanation and I would be getting a letter as such. I have never received the letter and the account is now restricted but not yet closed based on the information the Claims Department gave me on the phone.
