EBay spokesman Kevin Pursglove said the problem was discovered on Saturday morning (6 July) and affected sellers who had signed up for eBay's direct pay program.
Pursglove characterised the problem as "a snafu" but would not offer any details into what exactly went wrong. "It's fixed," he said, explaining that was all the company would say about the technical aspects of the problem.
After eBay discovered the problem, it notified its bank, which began reversing charges for the customers who had been double-billed. Pursglove said that if the double billing caused anyone to incur banking fees those affected should forward evidence of the charges to eBay. If the fees were indeed eBay's fault, the company will reimburse the sellers for the costs involved, Pursglove said.
Pursglove said an e-mail has already been sent to all customers affected by the problem.
