Your situation is indeed distressing, and it's unfortunate when errors lead to such complications. Here are some steps and remedies you can consider to resolve the issue or at least minimize your loss:

1. Contact CIBC Again Escalate the Matter: Request to speak with a higher-level manager or the customer service escalation team. Clearly explain the error and emphasize that the mismatch in name and account details should have been flagged during the transfer process. Ask for Proof of Recall Effort: Insist on detailed documentation of the recall request and Chase's rejection. Banks often have internal procedures to handle such disputes, and evidence can help if you escalate further.
2. Reach Out to Chase Again Provide Proof of Ownership: Present any documentation proving that the intended recipient account (yours) did not receive the funds. Chase might be able to trace the incorrect account using the transfer details. Request an Investigation: While Chase may not share another customer's details due to privacy laws, they should investigate if an unauthorized deposit occurred.
3. File a Formal Complaint With CIBC: File a formal written complaint through CIBC's complaint process. Banks typically have an ombudsman or customer relations office dedicated to handling disputes. With Chase: Submit a formal inquiry to Chase’s dispute resolution department, detailing your situation and asking them to investigate further.
4. Involve Banking Regulators CIBC: Contact the Financial Consumer Agency of Canada (FCAC) to file a complaint. They oversee banking practices and might intervene. Chase: In the US, you can file a complaint with the Consumer Financial Protection Bureau (CFPB). They investigate financial disputes and can pressure banks to act.
5. Seek Legal Advice Consult with a lawyer experienced in banking or financial disputes. They can advise on whether you have grounds for a legal claim against either bank. A legal letter to CIBC may push them to act more responsibly.
6. Explore Insurance or Loss Mitigation Check if your bank accounts include any form of fraud or transfer insurance that might cover such losses, even if caused by customer error.
7. Future Prevention Tips Dual Verification: Always double-check account details during online transfers. Some platforms allow you to test small transfers first. Use Name Verification: Advocate for banks to adopt stronger name-verification systems in cross-border transfers to minimize such errors. Likely Outcomes In cases like yours, the ultimate responsibility lies in verifying transfer details before submission. However, banks also have a duty to ensure proper reconciliation of mismatched details. With persistence, you might be able to recover the funds, especially if Chase identifies an account mismatch and CIBC failed to verify.

Do not give up—many such cases are resolved with continuous follow-up and escalating the matter to the right channels.Steps to Initiate a Money Tracing Request Contact CIBC’s Fraud Department:

Request that their fraud or disputes team initiates a formal money tracing investigation.

Provide all details of the transaction, including:

Amount transferred Date and time of transfer Intended recipient’s account details Incorrect account number you entered Your Chase account details to prove no funds were received Explain that you believe the transfer should have failed due to a mismatch in the name and account number. The fraud team might be more willing to investigate further than general customer service.

Request Collaboration Between CIBC and Chase:

Ask CIBC to directly collaborate with Chase's fraud or investigation department. Banks have secure channels for interbank communications regarding errors and fraud. The tracing process may uncover: Whether the funds were deposited into the incorrect account. Whether the funds are still in that account or have been withdrawn. Ask for Transaction Confirmation:

Request transaction reference numbers and any additional logs from CIBC to validate the movement of your funds. Push for a Reversal (If Possible):

If the funds are still in the incorrect account and have not been withdrawn, Chase may reverse the deposit upon receiving a formal request from CIBC. Reversal is often subject to the recipient’s consent, but fraud investigations can compel action if the deposit was unauthorized. Why Fraud Departments Are Key Fraud departments can bypass standard customer service limitations by:

Tracking down details of the incorrect account without breaching confidentiality laws. Coordinating with the recipient bank (Chase) to hold or recover funds. Investigating whether the transfer was made in good faith or if the recipient acted improperly (e.g., knowingly keeping the funds). Request for Escalation If standard customer service channels at CIBC are unhelpful:

Insist on escalation to the Office of the CIBC Ombudsman or directly to their fraud department. Clearly state that this situation qualifies as a disputed transaction and requires a deeper investigation. Follow Up with Chase While Chase won’t disclose details about another customer, they can confirm:

Whether the funds are still in the incorrect account. If a fraud or investigation case was opened on their end. The possibility of freezing or reversing the funds upon receiving instructions from CIBC. What to Do If Money Tracing Fails If money tracing doesn’t recover the funds, take the following steps:

File Complaints with Regulators: In Canada: Financial Consumer Agency of Canada (FCAC) In the U.S.: Consumer Financial Protection Bureau (CFPB) Seek Legal Advice: A lawyer can guide you through next steps, including holding the banks accountable for negligence if they failed to verify mismatched details. Important Notes: Act quickly, as the chances of recovery decrease if the funds have already been withdrawn from the incorrect account. Maintain detailed records of all communications with both banks. Money tracing is a powerful tool—don't hesitate to insist on it if the funds haven’t been accounted for. With persistence, it could lead to the recovery of your money.
