Managing an account: Checking or savings account

I am submitting this complaint regarding serious concerns involving my bank accounts and the handling of my account security. My previous bank accounts were compromised, resulting in the unexplained loss of approximately $3000.00. Despite my repeated requests, the bank has failed to provide any explanation regarding where these funds went. I instructed the bank to close the compromised accounts, and I was informed that they had been closed. However, when I requested written confirmation or account closure statements, the bank refused to provide them. Subsequently, I opened two new accounts and specifically requested that online banking access be disabled due to the security concerns surrounding my previous accounts. The banker assured me that online banking had been disabled on both accounts. Nevertheless, I continue to receive notifications indicating that monthly online statements are available for these accounts. In addition, my debit card has been randomly locking and unlocking without my authorization or knowledge. These unexplained changes have further heightened my concerns regarding the security and integrity of my accounts. I have contacted the bank on multiple occasions regarding these issues, but bank representatives continue to deny that online banking access exists and have failed to provide satisfactory explanations regarding the irregular activity affecting my accounts. Given the contradictory information, the unexplained disappearance of $3000.00, and the ongoing unauthorized changes to my debit card status, I have serious concerns regarding possible fraud, unauthorized access, and a breach of my account security. I further suspect that the institution 's failure to adequately secure my accounts and provide accurate information may be connected to the missing funds. I request an immediate and thorough investigation into the missing funds, written confirmation of all account closures, verification of whether online banking access remains active, a complete audit of all activity associated with my accounts, and an explanation regarding the repeated unauthorized locking and unlocking of my debit card. I also request that all records, communications, and electronic access logs relating to my accounts be preserved for investigative purposes.
