National Lottery operator Camelot has been fined £3.15 million for three errors, affecting tens of thousands of players, on its mobile app.
The first failure involved up to 20,000 users who were told their winning tickets were losing tickets when they scanned a QR code between November 2016 and September 2020, the Gambling Commission said.
The second involved 22,210 players who bought single tickets but were charged for and received two tickets.
All were either refunded for the duplicate wager or paid for their wins.
The third error saw marketing messages sent to customers who had self-excluded via Gamstop, a free service that allows users to restrict their online gambling, or who had been identified by Camelot as showing signs of addiction.
None of the 65,400 players were able to buy a National Lottery product through the app, however.
It comes amid a miserable few days for 에그벳 the operator, after it was revealed last week it is set to lose its licence to run the lottery after 28 years.
