Several Apple customers are complaining of fraudulent purchases made on their iTunes accounts, causing deductions of up to thousands of dollars.

An Apple spokesman, responding to queries on Sunday (July 22), would not comment on the extent of the problem but said that the company is looking into the matter.

Channel NewsAsia first reported Sunday that “dozens” were affected. The exact number is unclear, but the problem appears to have hit customers of most major banks here.

Mr Vincent Tan, head of credit cards at OCBC Bank, said that the bank had detected and investigated unusual transactions on 58 cardholders’ accounts.

“Upon confirmation that these were fraudulent transactions, we deployed the necessary counter-measures and are currently assisting the affected cardholders via the chargeback process,” he said.
