Unauthorised Transaction Contact Details

Direct answer and safest route

If you have spotted an unfamiliar charge on your bank statement or card, you must act immediately through your financial institution’s official channels. The safest route to address an unauthorised transaction is to log into your bank’s official banking app or online portal to freeze your card, or call the dedicated fraud hotline printed directly on the back of your bank card or official statement.

Before taking action, always verify that you are communicating through an official contact channel. Do not trust phone numbers, email addresses, or support links found in unverified third-party directories, SMS messages, or internet search adverts. ContactDetails.co.za does not collect, publish, or store unverified phone numbers or email addresses, nor can we process fraud claims on your behalf.

Official source checklist

Before initiating contact or submitting a dispute, cross-check your communication channel against this safety checklist:

• [ ] Is the phone number printed on the back of your physical bank card or on an official, printed bank statement?
• [ ] Does the website URL begin with https:// and match the exact, verified domain of your financial institution?
• [ ] Are you accessing the service through an app downloaded directly from an official app store (Google Play, Apple App Store, Huawei AppGallery)?
• [ ] Have you double-checked that you did not click a sponsored link or advertisement in search engine results?

Details users must not share

While bank support staff require certain information to investigate an unauthorised transaction, official staff will never ask for your sensitive security credentials.

🛑 Critical Security Warning

Never share the following details with anyone, even if they claim to be from your bank’s fraud department:

• Your Card PIN or ATM PIN
• Your Online Banking Password or App Passcode
• One-Time Pins (OTPs) or App Approval Notifications sent to your phone
• The 3-digit CVV/CVC code on the back of your card
• Remote access to your phone or computer (e.g., AnyDesk, TeamViewer)

Complaint or escalation options

If you have already reported an unauthorised transaction to your bank and are dissatisfied with the response, turnaround time, or claim outcome, you can follow an official escalation path.

Step 1: Internal Bank Escalation

1. Obtain a Reference Number: Always request and record the official case reference number from your initial fraud report.
2. Submit a Formal Internal Complaint: Request to speak with the bank’s internal Dispute Resolutions or Complaints Department.
3. Keep Written Records: Maintain a log of all dates, times, representative names, and written correspondence.

Step 2: External Escalation (Ombud & Regulators)

If your bank fails to resolve your issue within their stipulated turnaround time (typically 20 business days) or rejects your dispute unfairly, you have the legal right to escalate the matter to an independent body:

• National Banking Ombudsman (NBO) / Ombudsman for Banking Services (OBS): An independent official who investigates unresolved disputes between South African banks and their customers free of charge.
• Financial Sector Conduct Authority (FSCA): The market conduct regulator for financial institutions in South Africa.
• Payment Association of South Africa (PASA): Oversees payment system safety and rules regarding unauthorized debit orders and clearing processes.

Note: ContactDetails.co.za is an informational directory and cannot log, escalate, or intervene in complaints on your behalf.

Scam and safety notes

Scammers actively target South Africans who are attempting to report fraud. Be aware of these common tactics used to intercept unauthorized transaction reports:

• Fake Customer Service Numbers: Fraudsters post fake support numbers on social media, review boards, or search engine ads. Always double-check numbers against our guide on Fake Contact Numbers South Africa.
• Vishing (Voice Phishing / Impersonation): A caller claims to be from your bank’s fraud department reporting an “unauthorised transaction,” then asks you to read back an OTP or authorize an app notification to “cancel” the payment. This is a scam. Real bank fraud teams will never ask for an OTP to reverse a transaction.
• Refund & Courier Scams: Fraudsters may send an SMS claiming a payment was made or a package is pending, prompting you to click a link to reverse the charge. Clicking the link leads to a phishing site designed to capture your banking details.

FAQs

What is the best way to use the Unauthorised Transaction Contact Details page?

First, identify whether your issue requires an immediate emergency block (e.g., active fraud or stolen card) or a standard dispute (e.g., an unrecognised debit order). Use the official support routes detailed on this page to safely navigate to your bank’s verified, primary channels or related guides.

Where should users verify unauthorised transaction contact details?

Always verify contact details on the official website of your bank, financial institution, or regulatory body. Check the contact phone numbers printed on the back of your physical payment card, official account statements, or inside your verified mobile banking application.

What details should users prepare before contacting support?

Prepare your official account number, the exact date and amount of the unauthorised transaction, any merchant reference details listed on your statement, and your South African ID number. Never prepare or share your card PIN, online banking passwords, or OTPs.

What should users do if they cannot get help from their bank?

If your bank is unhelpful or denies your claim, request a formal repudiation letter and reference number. You can then submit a complaint to the Ombudsman for Banking Services (OBS) along with your case records for an independent review.
