The survey scam has been circulated via email and Facebook and there has been a surge in reports to the Australian Competition and Consumer Commission with 140 complaints received since the scam resurfaced at the start of September.
A Woolworths spokesperson took to Facebook to say the company never asks personal or banking details in unsolicited communications.
“All of our official competitions run from our Facebook page at facebook.com/woolworths and are posted on the Promotions & Competitions page of our website,” the statement said.
ACCC deputy chair Delia Rickard said that the scam had caught out a lot of unsuspecting people, and that Woolworths wouldn't honour the fake vouchers.
“Scammers impersonate well-known businesses to get their hands on your personal details. Once you have unknowingly sent your details to a scammer, they can steal your money – and possibly even your identity,” she said.
Rickard also pointed out that surveys often offer gift vouchers as a legitimate marketing tool, which is why so many people are being fooled by this particular scam.
“If you see one of these surveys, call the business’ official customer service line before starting it,” she said.
“Don’t rely on the links or numbers provided on the offer as this can link to a fake website or even a fake call centre.
“Don’t trust the legitimacy of a survey linked from social networking sites, even if they are recommended by people you know. Alarm bells should ring if you are asked to provide bank account or credit-card details. If you think you have provided your account details to a scammer, contact your financial institution immediately.”
