DDI Pocket will refund 5 million yen for overcharging handyphone users

DDI Pocket Inc. said Thursday it will refund about 5 million yen to some 900 subscribers to its data communications service due to overcharging.

The overcharges were caused by defects in billing software, and customers will be notified by phone or mail, the personal handy-phone unit of KDDI said.

According to DDI Pocket, the overcharges occurred between February and September under a service called Net 25, which offers customers 25 hours of data communications per month for a fixed fee.

Customers were reportedly charged even after they ended data communications, with overcharges adding up to 790 seconds more than the actual communication time.
