Damaged item delivered - service lacking

We ordered and paid for a stove through the online portal. I was notified that it takes 7-14 days for delivery. We were still in the process of moving, so I was happy to provide my new home address. I then got a message notifying me that the courier has collected to item and would notify me when it will be ready for delivery, only to receive a message from a tenant to say the stove has been delivered, without me being informed, and to someone that had no authority to sign for the item. Also take note that we had not moved to the address that was given for delivery yet. When we arrived at the premises on the day we moved in, we wanted to open the packaging but heard glass falling. Upon opening the packaging, we found that the front glass door of the stove was shattered. After numerous attempts to contact Makro to collect the stove and emails stating they first need to investigate we are left without a stove and without a means to cook at our home. The service has been poor to say the least and communication is lacking. I have no idea who to escalate this matter to, I'm at wits end.
