EXCLUSIVE: One of the country’s biggest online gadget stores has suddenly shut its doors, leaving hordes of smartphone, tablet, and camera buyers thousands of dollars out of pocket.

The websites of Yatango Shopping and its predecessor Mobicity turned completely white last week, hiding listings for the mobile devices, computers, and accessories the companies used to import and sell in Australia.

The white-out surprised customers, many of whom are still waiting for their technology orders to be fulfilled, and are now flooding online review websites and social media with complaints.

Orders from up to four months ago have reportedly gone unfulfilled, and the Yatango Shopping website remained available even though many employees were dismissed early this month.

One woman complained on Twitter that she could have “assembled a camera atom” in the 78 days since she ordered a $244 camera with the company, and another woman who paid for a phone on August 24 said she still had yet to receive it.

Sydneysider Tony, who asked for his surname to be withheld, said he paid Yatango Shopping $619 for a OnePlus 2 smartphone in late August but grew impatient when he hadn’t received the device by mid-October.

Even after cancelling the order in late October, Tony said he did not receive a refund.

“I finally gave up and went to my bank,” he said.

“While I waited, Yatango went silent. I took to Twitter and found others in the same boat.”

Tony eventually cancelled the transaction through his credit card company.

Other Yatango Shopping customers, including one man who pleaded for a refund for his daughter online, have received refunds through PayPal after Yatango failed to reply to its emails.

The surprise shutdown comes months after related companies Yatango Holdings and Yatango Mobile filed for voluntary administration.

But Yatango Holdings administrator, Cor Cordis partner Jason Tang, said Yatango Shopping customers were “not legally creditors” because that particular company had not gone into administration.

Yatango Mobile and Yatango Holdings are believed to owe millions of dollars to other companies, including more than $200,000 to a mining company for a failed acquisition bid in June, and more than $2 million to Optus Billing Services for reselling its mobile phone service.

On Friday, administrators published notice with ASIC to liquidate Yatango Holdings.

Yatango founder Andy Taylor did not reply to inquiries.
