Royal Mail has experienced a data breach where customers have seen the information of others users.
A statement on Royal Mail’s Click and Drop status updates website said: “We have been made aware there was an issue affecting Click & Drop that meant some customers could see other customer’s orders.
“As a protective measure, we have stopped access to Click & Drop temporarily.”
The issue was first acknowledge by the company on Tuesday afternoon when it said it was investigating issues with accessing Click and Drop and orders not appearing for users.
Later that afternoon the issue was being treated as “the highest priority”, the Click and Drop status updates website said.
Complaints on Twitter in response to the status updates had been mounting through the afternoon.
Some users reported seeing details of people’s orders, business’s order history and their customers details.
