Bad service

I am so frustrated with the service from FNB. I have a 32 day notice acc, and have been trying to withdraw from it since yesterday, an emergency withdrawal, for my electricity. I am aware of the penalties, cell phone banking says this service is temporarily unavailable, please try again later. THATS UNBELIEVABLE, since yesterday, I phoned Fnb the whole day, can you believe after holding for hours, the phone get dropped. I logged a complaint on their system, and no answer.... Why make it so difficult to withdraw your own money. I AM SO DISAPPOINTED AND CANNOT WAIT TO GET ALL MY MONEY OUT FROM FNB
