With the first orders of the Oculus Rift virtual reality headset slated to arrive in just over a month, a number of those with pre-orders awoke this morning to the disturbing discovery that their orders had been abruptly canceled.

Many of the reported instances seem to point to the fact that buyers were aiming to have the product shipped to unsupported countries or were otherwise misrepresenting their order. Oculus has initially limited orders of the headset to buyers in 20 countries.

This bout of cancellations comes only a day after launch details were released regarding Oculus Rift competitor HTC Vive. The Vive headset will notably include pre-order availability in China and a few other countries not supported by Oculus at launch.

Oculus provided a statement to TechCrunch on the cancellation, noting, “A small number of pre-orders were unable to be processed and as a result were canceled. Customers can contact support if they have a question about their order.”

A number of Reddit/Twitter users specified that they believe they were unfairly scooped up in the bout of cancellations after pre-ordering the device while traveling abroad or by having differing billing/shipping addresses.

A representative from Oculus, Reddit user William_VR, commented in a thread titled “Order cancelled??” that the company is tuned into the concerns being voiced.

“We’re aware that there are questions on pre-orders and cancellations and we apologize for any confusion this may have caused. Please contact our support team at https://support.oculus.com if you have questions about your specific order cancellation.”
