bad attitude

When i went to keywest fnb I had the worst experience ive had since I have been banking with them. First of all the bankers were sitting on the couch in the INCORRECT que. As I approached the correct que to pick up my card, the lady had the nerve to tell me I have to sit on the couch because this is where the que is. Infront of me there was already about 10 people with 1 lady helping them. She had all the time in the world. When I asked the guy working there where I can file a complaint due to slow service and people in incorrect ques he simply said they have no such thing. He then said I would receive an sms and should reply but did not take any of my details. He did not help us but simply walked away. I am dissatisfied with the service I received today.
