The website is back after what’s considered to have been an internal fault changing the site on Sunday.
Separately, the company said it was aware of folks receiving scam emails masquerading as having been sent from Argos.
The company advises customers not to hand over personal details after receiving unsolicited emails. It said it had not suffered a cyber attack.
“We have identified and fixed the issue and our site is now up and running.”
“We apologise to any customer who has tried to contact us unsuccessfully today and we are working to respond to all enquiries as soon as we can.”
Argos’s web site endured troubles for 2 days following a revamped design of the site last year.
It exhibited an error message on some computers, but not others, saying access was blocked due to a “high volume of visitors”.
