UPS, delivered my imported package with contents inside missing and tempered with as a result I’ve lost over $1000(R15k) + with of product

worst service ever I ordered products from HK however when I received my shipment today 10/03/2022 there are 3 contents missing from the package, I’m supposed to receive 12 iPhones as per invoices that I bought from HONG KONG but ONLY received 9 with contents inside package 📦 opened and tempered with, clear sign of theft, first time using UPS I have never been disappointed, it’s funny the box is even written it has 12 contents, as well as per customs declaration and documentation inside but I only found 9 when I opened the box,
