How'd you go with lodging a complaint with AFCA? I looked at lodging a complaint with AFCA but because Shopify isn't listed I don't seem to be able to go any further. There was a chargeback made, but I'd refunded over 1/4 of a significant sale because I was unable to supply the entire order. Shopify took the entire amount, plus the $25 chargeback fee, without taking into consideration the refunded amount.
I am not sure how you may go about that however, in your relation with Shopify chargeback cases. As a merchant wining the charge on Shopify is impossible to none matter the amount of proof you produce with them. With PayPal it's a little bit better because, they give you time to handle the situation before it handles through them!
Shopify said we had until the 29th to respond & then took the money less than 48 hours after the initial email. I've already started legal action. Our local state MP is Kevin Anderson. He's the person who issues fines to rogue companies. To find out how savage he is look up Camera Sky & the size of the fines.
