Sony Japan has accidentally erased all information obtained from PlayStation owners who entered to win a 20th Anniversary PlayStation 4. Those who purchased PlayStation 3, PS4, Vita or Vita TV between December 4 – January 15 were handed a calendar with a code which entered them into the contest.
Somehow, all data collected from the customers was erased and cannot be recovered. Sony didn’t provide information on how the data was lost.
Customers can now re-enter the contest by sending all required information in again.
