Walmart has launched an investigation after a shopper was charged for an additional 22 items. 

After returning home and reviewing her receipt, she discovered that the retail giant, the largest in the world, had mistakenly billed her for 24 items instead of the two items she had purchased.

The frustrated customer went on media this week to complaint that Walmart still hadn’t issued a refund a month afterwards.

The error is said to have occurred while checking out at a South Carolina store on March 1, when she was charged an extra $186.65 for items she didn’t purchase.

‘@Walmart @WalmartWorld @BankofAmerica FRAUDULENTLY CHARGED MY ACCOUNT AT store#03367,’ she wrote in an X post. 

‘I bought 2 things and they added 22 and I have no f****** recourse.’

Walmart requested the shopper send the a DM with more information, to which the shopper claimed she already did.

The incident comes after Walmart lost its title as the nation’s biggest retailer.

Walmart advised its customers to report any overcharge to an employee immediately.

Customers may need to show their receipts to employees to provide proof of the overcharge and price difference.

Shoppers are always entitled to the lowest advertised, posted, or quoted price in stores or online.

Stores are required to honor the products’ prices, even if the cost has increased since the initial purchase.

Walmart usually reaches out to shoppers who’ve shared their complaints and incidents on social media.

In most cases, Walmart will request that the customer send more details through a social media app or email.

Customers can also contact Walmart by phone to discuss any incidents.

Despite their offering many resources, the retailer does not specify when its investigations over any matters are completed.

Walmart has a long history of being accused of overcharging customers.

The retail empire made headlines after a customer filed a class-action lawsuit claiming it overcharged its customers on certain weighted items in 2022.

The unidentified shopper claimed Walmart falsely inflated product weight, mislabeled items, and overcharged clearance products sold by weight.

Walmart denied wrongdoing but agreed to a $45 million settlement last year that would go to customers who qualified for refunds.

Another minor incident that occurred this year involved a customer who claimed they were overcharged for a computer mouse in February.

The shopper explained their mouse did not work after purchasing it in a store and claimed they couldn’t return it because the serial numbers didn’t match.

‘It took everyone working together to f*** this up so bad. How did everyone get so incompetent?,’ the aggravated shopper wrote on X.

Walmart asked the customer to send more details about the matter via DM, but it’s unclear what resulted from the investigation.

Walmart’s recent fourth quarter revenue was a 4.1 percent increase compared to its results this time last year.

Its competitive US and international sales increased by 4.6 and 5.7 percent respectively.

Despite the success, Walmart was one of the retailers customers believed would be strongly affected by the latest tariffs put in place.

However, experts believe Walmart+ will serve as a secret weapon in keeping its finances and customer numbers on track.

Daily Mail has reached out to Walmart for comment about the incident.
