School fees

Hi. I am a working single mother with sole custody. I just paid full deposit of my child fees $880 including registration for next year child care in Nursery. I was being told that the childcare will only start processing those documents on the first day. So means i need to fork out $780 for school fees from Jan to when?? I dont know how the processing time will takes? Anyone can advise me. I find it ridiculous if the processing takes longer. Documents all submitted n i did asked the staff to check if anything missing. She said all in. How??
