Mazda5 Fuel door release latch stuck

I drive a 2010 Mazda5 and today for the first time the fuel door release latch below the driver's seat would not move. No matter how much force I applied, I could not lift the latch. As a result, I am unable to refill the gas tank. All the local service stations were closed today for Christmas Eve and will be closed tomorrow as well. Can anyone suggest how to release the latch so that I can refuel?
