Product: Checking or savings account

My Bank of America checking account was comprised and 3 fraudulent charges were made over the holiday period of 2018.

The bank temporarily refunded the fraudulent charges as well as granting a {$100.00} hardship temporary loan.

Following several weeks after the claim had been filed, the bank withdrew all the funds, including the fraudulent charges stating the activity in question was valid and posted correctly to my account. 
I am an elderly person ( XXXX XXXX XXXX ) who does not drive and live nowhere near where these fraudulent charges were made. I am on a fixed income and have faced extreme hardship due to not only the criminals who originally stole my money, but also the BofA who has put me through a tremendous amount of stress. 
Bank of America has essentially criminalized me and forced me to prove that the fraud is not mine. Shouldnt the bank be doing the investigating? 
I have made countless attempts to communicate and escalate my case with the bank, without success. Whenever I am able to reach a person at BofA, that person is unable to provide any information and is basically reading me a scripted response. There is no escalation procedure, no management, no supervisors and the people I am able to speak to are unable to provide any answers and refuse to escalate to a superior. 

Below are the dates and details of the events : XXXX - 3 Fraudulent charges made at XXXX. 2 charges made at XXXX in XXXX XXXX, NJ for {$250.00}. 1 charge made at XXXX in XXXX, NJ for {$260.00}. Total amount of fraudulent charges made to my checking account = {$760.00} XXXX - Fraudulent charges posted to my account.

A claim is opened and {$100.00} hardship loan is deposited to my checking account.

XXXX - Above mentioned letter received and phone call made to BofA to dispute the decision and reopen the case since the 3 charges were, in fact, fraudulent and not made by me. Documentation is requested by me from the bank as to how the determination was made - no documentation has ever been provided.

XXXX - Called bank to reopen the case Agent confirmed that case would be reopened and the the case was originally closed due to other non - fraudulent charges had been included in the evaluation of the case.
