Paying for an item I don't have

I received a laptop and it went faulty the next day. The unit was collected by RAM Couriers on 14 July 2021. After phoning Vodacom several times on *** to enquire about the progress, I was told that the package "has not been booked in at the couriers" It is NOT my responsibility to sort out Vodacom's internal processes but what is my problem is the fact that I have been billed twice for an item I don't have. I have also had no communication from Vodacom, it has been my responsibility to contact them all the time.
