Marks and Spencer Group PLC (LSE:MKS) has been forced to keep digital orders suspended for another day due to problems sparked by a cyber attack last week.
Customers of the chain using the website and app have been left unable to make online orders for a fourth day on Monday, 28 April.
After reports first emerged the previous Monday, the FTSE 100 group issued a statement on Friday saying orders on the website and app had been temporarily stopped "as part of our proactive management of a cyber incident".
Click-and-collect orders placed online had been paused since the weekend too, with the group also promising to refund orders placed by customers on Friday.
Newspaper reports suggested the cyber incident it a ransomware attack by "a criminal gang", essentially holding the company to ransom.
