Law question. Please help

My bank account was the target of fraudulent activities. Chime Financial has previously rejected my requests four times in a row, stating that there was no error, even though I have already requested and presented statements and documents regarding these unlawful transactions. The efforts taken to return this cash to me have left me feeling let down. Should I sue the firm and employ a lawyer at https://consumerattorneys.com? Please offer me any guidance that would be helpful; I truly need it.
