A glitch charged users twice for purchases

Bank of America said it is refunding Apple Pay users who were charged twice for purchases due to a glitch in the system.

Approximately 1,000 transactions were impacted by a BoA app glitch, a bank spokesperson told TIME. Refunds were issued on Wednesday.

Apple launched its new mobile payment service Monday—the latest major expansion of service by the tech giant. With it, customers can use their smartphones in lieu of debit and credit cards at dozens of retailers including Macy’s, Chevron, and Walgreens. Shortly after the launch, Bank of America customers took to social media to gripe about being double charged.
