IT glitch slugs 78,000 Sydney motorists with incorrect charges

“This cannot continue to happen,” she said.

In some instances, it was not just a simple case of refunding the money, Ms Ward explained, because the incorrect road toll charges had triggered a top-up payment on some drivers’ E-Toll accounts.

A top-up payment is automatically processed from a user’s bank account when their minimum E-Toll balance is breached.

“Those are being worked through,” Ms Ward said.

“I was furious when I found out about this second lot.”

Last month Transport for NSW was forced to apologise after a “system error” led to 45,000 customers being overcharged.

Customers were overcharged with “duplicate transactions”, meaning travelling on toll roads cost users double.

Ms Ward said the “majority” of customers have had incorrect charges refunded to their accounts.
