Playstation Store Game refund

Sony has a 14 day return/refund policy on certain items purchased from the Playstation store taking that you have not started to stream/download this product. I have accidentally purchased a game for over R700. I immediately went to request a refund but the customer support was closed due to it being late at night. I waited until the following day to request my refund via email as this is the only option. I have tried doing it through the chat system online where I was placed in line of +-400 people. I gave up and waited for the email where I received a Case number, the next day I rep**** to do a follow up just for me to receive another case number. after another day of no feedback, I request another cade number. Till this day I have not received any help the game was purchased on the 1st of September. I need my refund but I am not getting help.
