Product: Checking or savings account

My son has an account with Current on which I am the XXXX. My checking account and debit card are linked to his account ( essentially, we both have an account ). Current is a financial technology company, not a bank. Banking services provided by XXXX XXXX XXXX, Member FDIC, and XXXX XXXX XXXX, Member FDIC. 
My family and I were vacationing in XXXX, FL from XX/XX/2023 through XX/XX/2023. On XXXX XXXX, my son saw some pending charges that were not his and reached out to Current to try and stop, however after speaking to my son after he spoke to that gentleman, we have come to the possible realization that he was not affiliated with Current. I had also received fraud alerts from my separate personal bank- XXXX that they had blocked XXXX transactions in the amount of {$5100.00} and {$1000.00} from Current. The person that had illegally accessed my son 's account and digital debit card had initiated XXXX transfers to the Current account from my linked checking account. Unfortunately, I was unable to reach out to Current until XXXX XXXX because the person who unlawfully accessed the account changed our phone numbers and locked us out of the account and Current is only available via chat on the weekend and that chat feature was in the app that we could not access. Monday was a holiday ; therefore, I was able to reach back out on XXXX XXXX. A new digital card and debit card were issued. I provided the receipt/transaction numbers for the XXXX unauthorized transactions- totaling {$69.00}. Yes, this is a small amount but that was my son 's paycheck for the recent days he'd worked, and it was wrongfully taken and Current refuses to do anything about it! My dispute has been denied XXXX times. I asked what additional documentation was needed and was told a police report. I filed a police report with XXXX Police XXXX ( the transactions were made at XXXX in XXXX, XXXX XXXX hours away from XXXX XXXX. The police XXXX informed me that he would be unable to pull video footage because the transactions total were under {$100.00}, but he said he would file the report. I provided that case number as well as a screenshot of my son 's location on XXXX XXXX to Current. The app that provides GPS location is XXXX. My dispute was still denied. I was informed that my case had been reviewed, including evidence provided by the merchant ( XXXX ), and concluded no error occurred. I reached out to XXXX 's store XXXX to confirm whether or not Current had indeed reached out for a statement or documentation. The store XXXX that I spoke with said there had been XXXX contact. I provided the date and times of the transactions and she was able to pull them up. The person had purchased gift cards on XXXX  of the transactions and put the funds stolen on those gift cards. I have requested all documentation proving an investigation was conducted as well as how their determination was made. This financial institution is absolutely refusing to uphold their fiduciary responsibility to us as a client that entrusted our money with them, trusting that it was protected. It is their responsibility as an FDIC insured financial institution to refund the unauthorized and illegally obtained funds.
