They've ****** my money and couldn't care less

I've been trying to get a missing item from my last order deliver (MAK***). The driver gets here with 2/3 of my parcels, makes a lackluster attempt to follow up on the matter and delicates it to me. I have spent hundreds on airtime calling in their contact center for the issue to get escalated and completely disregarded 2 days later. This has been happening for 2 whole weeks. I am deeply disappointed at this ridiculous loop they have me going around all due to the incompetence or the courier.
