Refusal to acknowledge damaged inverter

It seems Makro does not want to take accountability for damages incurred between their courier services and store. I complained about a damaged inverter which got damaged between the courier company and the Bloemfontein store but they are absolving themselves by saying they don't have a handover document. I'm not sure who is meant to provide this document as I merely a consumer. If Makro does not attend to this matter, I will have to escalate it further.
