Problem with a lender or other company charging your account: Checking or savings account

My Chime account was accessed. I disputed the $43.00. Someone fraudulently logging into my chime account. They tried to send money to other chime accounts, but it was denied. My phone number was removed and changed to the fraudulent persons number. I noticed the email that my phone number was removed, I logged into chime and saw an apple device is logged in, I have android. I quickly removed device, but they logged back in. They quickly made a $43.00 charge on my account as this was all I had in the account. I removed there device again, changed passwords, and replaced all cards. Chime allows for card numbers to be seen on the app. I disputed twice. I sent evidence. Chime only denies claims.
