SEPTA said that it will issue fare credits to customers who were charged $2.90 instead of $2.50 for a ride on Monday, the agency announced.

The mass transit system said the incorrect charges impacted some customers who bought bus fares by tapping Key Cards or other contactless methods of payment.

The agency initially planned to raise fares to $2.90 on Monday as part of its changes due to a financial deficit of $213 million, but a judge paused the move along with all planned service cuts last week.

In a statement, SEPTA apologized for the overcharges and said customers impacted will receive a 40 cents credit in their accounts.

The refunds will be issued “as soon as possible,” SEPTA said.

The court case that forced the pause in service cuts and fare hikes is set to meet again on Thursday, Sept. 4.
