A number of AMP, Credit Union Australia, and Teachers Mutual Bank customers were hit with duplicate charges to their Visa debit cards on Saturday thanks to a systems glitch with payments provider Cuscal.
CUA today notified its customers of the issue and apologised for the inconvenience.
"We are aware that some Visa debit card transactions made by members of CUA and some other financial institutions on Saturday 16 April have been processed twice," it informed customers.
"We are working to resolve the issue and refund affected CUA members as soon as possible."
AMP and Teachers Mutual Bank both confirmed to iTnews their Visa customers had also been debited twice.
All are understood to use Cuscal as their payments switching service. The provider also lists the likes of MyState, among others, as customers. The bank has been contacted for comment.
None of the banks detailed the number of customers were affected or how many transactions were processed twice.
Cuscal has been contacted for comment.
Last August Commonwealth Bank customers were charged twice for credit card transactions, and several months earlier a PayPal glitch duplicated payments for the company's customers.
NAB also suffered a similar problem in 2014, when an unspecified "technical error" in its payment system caused Visa debit users to be billed twice.
