Traveled 3 hours to find a notice on the door that they are closed!

If I could give no stars I would! I traveled 3 hours to get here today only to come and see a notice on the door that says they are closed! This is my third trip here without help from anyone! How can you close without notifying people in advance? Absolute waste of my time, effort and money to get here today! This is the only time Educators have to do their SACE while on school holiday!!! What pathetic service!!!
