Tesco’s website and app have gone down after hackers ‘tried to interfere with the systems.’

The supermarket giant has been experiencing issues with its online shop for nearly 24 hours.

Customers trying to access products are met with a message which states: ‘Sorry, there’s currently an issue on our website.

‘We’re busy fixing it right now and hope this doesn’t cause you too much inconvenience. Please come back and try again later. Thank you for your patience.’

It means anyone trying to organise a delivery or revise an existing booking is unable to do so.

The problems are being caused by ‘an attempt to interfere with the system’, a spokesman confirmed.

He said: ‘Since yesterday, we’ve been experiencing disruption to our online grocery website and app.

‘An attempt was made to interfere with our systems which has caused problems with the search function on the site.

‘We’re working hard to fully restore all services and apologise for the inconvenience.

‘There is no reason to believe that this issue impacts customer data and we continue to take ongoing action to make sure all data stays safe.’

Hundreds of people have taken to social media to complain about the issues.

One woman said she has a delivery booked for tomorrow and has only added random items so far so urgently needs to make changes and additions.

She added: ‘I do not want to cancel as it is hard enough to get a slot, just want to add the things I need.’

Another woman with a similar issue said: ‘I need to edit my shop for tomorrow (currently all it is is a banana) I always edit the shop the day before…. can I get a full refund if your system isn’t back up and running?’
