Online order not delivered but Legit hasn’t refunded me

Placed an order on 08/12/2024 and I paid using Happy pay. To date the order hasn’t been delivered and I only discovered today that the Parcel Ninja delivery truck was involved in an accident hence the delivery never took place. I keep emailing Legit to request for the order to be cancelled so I can be refunded but I am being ignored. Also contacted the customer care line but I didn’t get assistance from them neither. Happy Pay has already taken an installment from me and I want my money back.
