Car was excellent, except unable to contact Routes car rental service desk

Our flight was cancelled and then delayed. We booked the car to pick up at 8am, but need to delay the pick up to 6:40pm on the same day. We couldn't contact Routes to deferred the pickup time. It was stressful initially not knowing if they will keep our booking or still charge as no show. Otherwise, we are happy with the condition of the car.

I contacted QEEQ help lines couple times, they have been helpful.
