BAM Lightspeed Bundle Overcharged

I pourchased the Lightspeed Bundle for The Mandalorian (Beskar Armour) Journey Guide and have been charged for it twice.  I had $68.09 in my Apple ID funds and since checking after buying the bundle I have $6.09. The bundle was only supposed to cost $30.99 AUD and it appears $61.99 AUD has been deducted. I have received the Bundle but would like to know how i recover my lost funds. My Ally Code is 442-779-693
