Vodabucks

On the 2nd of February, my daughter bought an airfryer on her vodabucks app - the transaction didn’t go through and was cancelled sbortly after. We did not get our refund so I called the customer care line to bring it under their attention - I have repeated this process numerous times now; calls to the operators and supervisors and emails to vodacom’s customer care service - they have logged the cancellation twice in February and despite promises that they will follow through, the only respons so far has been that the vodabucks accounts department does not respond to the emails the supervisors has send them. It is going on two months now and I still haven’t received my refund. No one seems to be able to help me and no one calls back with any progress? We paid for a product that we did not receive; we cancelled the order and followed all the necessary steps to obtain the refund - all to no avail. Please help!
