Can You Sue a Bank If an Unexplained Technical Glitch Causes Your POS Terminal to Double-Charge a Customer in Nigeria?

Yes. A merchant or customer can sue a commercial bank for negligence and breach of contract if its Point of Sale (POS) terminal system repeatedly double-charges transactions.

Under the Central Bank of Nigeria (CBN) Guidelines on Operations of Electronic Payment Channels, banks owe merchants and consumers a strict duty of technical diligence.

When a POS terminal executes duplicate debits for a single purchase, the acquiring bank and issuing bank are legally bound to reverse the error promptly.

Step-by-Step Procedure to Resolve This Legal Matter:

  1. Preserve Contemporaneous Evidence: Collate physical receipts, verified bank timestamps, stamped letters, and electronic communication logs prior to formal intervention.
  2. Deliver Statutory Pre-Action Notice: Issue a formal written demand outlining the specific statutory breach and giving the opposing party statutory time to remedy the grievance.
  3. Engage Accredited Legal Counsel: Initiate judicial proceedings before the competent court of record or submit an official petition to the relevant regulatory commission.

Under CBN Consumer Protection Regulations, erroneous POS duplicate debits must be reversed automatically within 24 to 48 hours.

Key Evidential Considerations & Statutory Benchmarks:

  • Documented statutory breach and verified timeline of events.
  • Jurisdictional competence of the regulatory agency or superior court.
  • Contemporaneous written correspondences, notices, and financial records.
  • Quantifiable proof of pecuniary loss or civil rights violation.

“The rule of law ensures that statutory rights and duties cannot be compromised by informal arrangements or administrative fiat; every citizen has the constitutional right to due process.”
— Nigerian Legal Precedent & Constitutional Jurisprudence

If the bank’s technical failure causes a merchant’s customers to be double-debited, damaging the merchant’s business reputation and causing customer riots, the bank is liable.

The merchant can sue the acquiring bank for commercial negligence, breach of merchant service agreement, and general damages for loss of business goodwill.

Customers affected by POS double-debits should lodge formal written complaints with both the merchant and their issuing bank, requesting transaction reference numbers.

If the bank fails to reverse the duplicate debit within statutory timelines, submit a formal complaint to the CBN Consumer Protection Department at [email protected].

You can also instruct a banking litigation attorney to file an action in the High Court for recovery of the debited funds and substantial compensatory damages.

Courts in Nigeria have consistently awarded damages against commercial banks whose careless electronic payment glitches caused retail consumers financial distress.

Preserve all POS transaction printouts, error slips, bank debit alerts, and customer complaint logs as documentary evidence for court.

Electronic payment systems must operate with technical accuracy. When financial institutions fail to resolve POS double-debits, the law provides full legal redress.

In Nigeria, statutory rights and constitutional protections exist to shield ordinary citizens from exploitation, abuse of official power, and predatory commercial arrangements. The courts remain accessible, and regulatory bodies actively intervene to hold wrongdoers accountable.

Do not allow ignorance of the legal system or fear of intimidation to stop you from asserting your lawful rights. Consulting a certified Nigerian legal practitioner early provides strategic clarity and protects your personal and commercial interests.

Taking decisive, well-documented legal steps promptly is far more effective than waiting until violations cause permanent financial or emotional damage. Nigerian courts consistently reward diligent parties who assert their legal rights without unreasonable delay.
