Cash App complaint: Fraudulent transactions

On February 5, 2021 there were 11 attempts to remove funds from my account all within minutes of each other beginning at 3am. Unfortunately two of those attempts were successful totalling $516.50. My funds were sent to unknown individuals who I had never even heard of let alone sent money to. It was brought to my attention that someone created a duplicate account in my name using my debitaccount information and removed the funds without even needing my personalized code I created for security. I’ve tried reaching out to cash app several times via email because they don’t have a live customer service but even after supplying all the information they requested down to the make and model of my phone as well as my location and I still have gotten no where. I filed a dispute with my bank and to my surprise Cash app denied my claim and lied on me stating I had sent funds to these individuals before. I have my complete cash app history to prove they are liars and crooks! I absolutely can not lose out on $516 with my five children. Please help me!
