Fraud Characteristics by Phone
- If the number is a mobile number, it is likely to be a scam. If it is a landline number, it is recommended to double-check. Hotline numbers (numbers starting with 1800, 1900) can be trusted.
- Provide relevant information to establish trust, such as the time of purchase and the authentic product purchased.
- Beware of incredibly attractive and hard-to-believe deals, such as buy 1 get 2 or 3 products, or buy 200,000 and get 1 million or 2 million.
- Be cautious when additional services or accessories related to the main product are being sold, such as warranty extensions that require customers to pay a fee to continue using the service. We currently do not offer any warranty extension programs.
- Be alert to promotions with very short time frames that end on the same day. If you don’t participate immediately, you may miss the opportunity.
- Avoid situations where customers are required to pay or transfer a fee in advance before receiving rewards from a program.
- Verify the account number required for transfer, ensuring it is a familiar and legitimate company account number.
What to Do When Suspicious of a Phone Scam
- Research the brand or company that sent the offer by searching for their hotline number online. For example, search for “Samsung hotline” or “Sony hotline” on Google.
- Accurate information about the official hotline of the brand or company will typically appear in the search results without the word “Advertisement” or “Ad”.
- Call the hotline number of the brand or company to confirm the offer received. Only confirm purchasing orders and services through this hotline number.
