ASDA customers are unable to edit online shopping orders due to a tech glitch.
The supermarket said the issue means any amendments to orders for today haven’t been recorded.
If you made changes to your shopping basket for a delivery today, you could get the wrong items.
You can return any products you don’t want back to the driver and the issue has been fixed for future orders, Asda said.
The grocer added that customers will be refunded for goods they added to their shopping but have not received.
Furious shoppers took to social media to vent their frustration.
“I have lots of missing items due to this,” one customer said.
“I think an apology would be in order rather than just saying “the issue has been fixed”.
“Really really annoying. My printout of my order bears no relationship to the online version of my order. Add in substitutions and it is a mess!!!!”
A customer wrote on Twitter: “My order was confirmed at 8pm last night and also been charged for 12 items I haven’t received.
“No apology or explanation from the driver either. It’s not good enough.”
Another added: “Not good enough. Now had to reorder at extra expense.”
The Sun has asked Asda how many online shopping orders have been affected by the glitch.
Asda said in a statement today: “We are experiencing a technical issue with amendments for orders today.
“If you receive items you removed & you do not want them, please hand back to the driver.
“Any items added to your order will not be in your delivery. The issue has been fixed for future orders.”
If you’ve received the wrong items you can return them to the driver when they drop off your shopping.
You will be refunded for those products, and it can take three to five days for the money to be put back in your account.
It could take longer at busy times, Asda said.
You can also ask for a refund up to five days after receiving your order by logging in to the “your orders” section of your online shopping account.
If you’re missing items that you added to your delivery, you will also get the money back.
Make sure you double check your shopping carefully, so you don’t get charged for things you don’t want or haven’t received.
Asda isn’t the only major retailer to suffer a glitch this week.
Boots was forced to delay its 70% off sale due to a tech problem.
