The drop-off location closed at 1 PM, but there was no reminder when we rented the car, and the system did not display this information. We had scheduled our return for 4 PM, but when we arrived within the designated time, there was no one to assist us. After calling for assistance, we deposited the keys into the self-service drop box. The rental company didn't process our return until two days later, charging us for an additional two days... The issue remains unresolved after communication.
