school subsidies

I enrolled my girl into toddler class this year may 2019. Applied for both working mom & additional subsidies. The application dragged for 2mths and finally approve Wef 1st July. Do I still get the refund for the past 2mths additional as I paid full? Let me rant a little.. I settled the application myself, the school do no shit. Principal n admin pushing the blames to each other and then to ECDA. 0 calls from them to follow up on the application. Ridiculously rude to parents, admin probably has 0 knowledge. Everyt also don't know. ?
