Product: Checking or savings account

Thursday, XX/XX/XXXX I received an email from J. P. Morgan Chase Bank saying something to the effect that something was wrong with my account. I logged in and received this : " We locked your account to protect it from suspicious activity ''. 

I called the number. I spoke with someone who was pretty difficult to follow but essentially said that my account had been terminated and that Chase has the right to do this under the agreement I entered into with them. I asked what my recourse is. I then asked to speak to a supervisor. I got a supervisor who said the same things. My 2 accounts had been closed and I couldnt do anything about it. I asked if I was getting a letter about this and when. She said yes that I should be receiving a letter shortly. And she said that the balance in my accounts would be sent to me within 10 business days. 

Here is info she gave me over the phone : All my accounts are restricted. 
Bank decided to end the relationship. 
I will receive a letter in the mail. 
Account will close in 10 business days. Then a check is sent to me. 

Pre-authorized debit card transactions will be paid Checks or automatic payments will be rejected Direct deposits will be deposited but will be delayed by 2 business days -- -- -- -- -- -- At my local Chase Bank branch, the person helping me with my accounts, first said that my joint account was restricted too. She thought she could fix the problem but then she found out by calling some other department, that Chase had terminated my relationship with the bank. She filed a complaint on my behalf but couldnt give me a reference number/complaint number on the spot. 
-- -- -- -- -- -- Received a letter dated XX/XX/2020 that only said this as an explanation : " We're doing this because of recent activity on the account, or because you didn't provide information we requested. '' -- -- -- -- -- -- - XX/XX/2020 I called Chase and got transferred to Operating Loss Prevention Department. I asked for the status of my complaint and have now been on hold for over 45 minutes after being told just to hold on for a short time. 

Talked to supervisor, XXXX. He gave me my Case ID # XXXX. He said someone on the escalation team had been assigned to it on XX/XX/2020. He said he saw no additional notes in the Case. 
-- -- -- -- -- -- - XX/XX/2020 Called Chase. 
XXXX XXXX was the Customer Service person I spoke to. I cant speak directly to the person assigned to the case. I gave XXXX information to put into my case and asked him to enter it into the notes of the case. He said he did He confirmed my call back number. 
-- -- -- -- -- -- -- XX/XX/2020 XXXX XXXX from Chase called. He left a vmail and said he would call back today. 
I called XXXX. He is front-office. He is not seeing any notes added to my case from XXXX XXXX -- the person I spoke to, 2 days ago. 

XXXX said he would contact the back office RFP to see if he could get any information. They responded - no further information from the back office. They are closing my account without any tangible explanation. 

-- -- -- -- -- -- -- -- -- -- - Chase closed 3 accounts - 2 personal ones and one joint one with my spouse. The amounts in these accounts were roughly : $ XXXX $ XXXX {$2700.00}. 

I checked my credit reports, credit score, XXXX, my credit card accounts and everything checks out fine. No suspicious activity. Everything is stellar with my credit, I have no debt except a mortgage and I have a very stable job in the computer industry and am well paid. This doesn't make any sense. I was even told that I couldn't open a Chase account in the future -- not that I want to anymore ... My spouse, XXXX children and mother-in-law all have accounts at Chase.
