Customers of Play.com have contacted the BBC to report problems with the online retailer’s ordering system.
Many customers have received e-mails from Play.com reporting the despatch of an order they did not place.
Those opening the orders found contact details, including names and addresses, for other Play.com customers.
On some forums customers said they were told that a “system error” was behind the sending of the e-mails.
In a statement a Play.com spokesperson said: “We were alerted to an incident that appears to have affected some customers for a short period of time in the early hours of this morning, and the first thing we’d like to say is that we apologise for any inconvenience our customers have experienced as a result.
