Thousands of furious Costco members around the country claim they have been stung by a “glitch” that saw their bank accounts charged twice for fuel.

The issue was brought to light on Tuesday, with many customers reporting the “glitch” online.

“Can someone help why my account is now negative? I got fuel this morning about 45 mins ago and it’s taken it twice?” a WA Costco customer asked.

“DANGER COSTCO USERS. I have been charged twice for my fuel at Costco Today,” another customer warned.

“They have had lots of people complain about it and they say they have tecno’s working on it. Please avoid if you can as you will loose a lot of money. I have been charged $285.00 for a $135.00 worth of fuel (sic).”

An authorisation hold is put on the customer’s debit or credit card before they can refuel at Costco.

For example, a customer might select a pre-authorised amount of $75 but then pump $50 worth of petrol.

The $50 will be charged to the customer’s card and the pre-authorised $75 will be released after the transaction.

Customers say the “glitch” resulted in the pre-authorised amount being charged to their card on top of their fuel purchase.

Generally, you’d encounter these holds when booking a hotel room or hiring a car.

The practice is common in the US to ensure people don’t steal fuel, according to msn.com.

“It’s not holding the authorised amount, it’s charging the authorised amount and then a second charge for the fuel taken. It’s apparently a nationwide Costco glitch that they have been aware about all day and continued to let people fuel up and be over charged,” another WA customer shared.

“I inserted my card and was charged $450 for 3/4 of a tank of diesel, so I went back at 4pm to ask for a refund and was told it could take up to 14days and there’s nothing they can do. I told them they should be putting up signs letting people know that they are going to be charged twice and let them decide if they wanted to risk it.”

On Wednesday, a warning sign was placed on fuel bowsers at Costco Casuarina.

“Due to an ongoing payment processing issue, we can only accept credit card payments. Payments done via other methods may result in extra charges. Sorry for the inconvenience.”

Customers who contacted Costco about the “glitch” said they were told it was a nationwide issue impacting prepaid systems across the board.

One customer said they were told their prepaid amount would be refunded within three business days.

Costco was contacted for comment.
