Waiting on my package for over a week, shocking customer service

My package was handed over to Fastway on 30 December and today, on the 7th of January it still hasn't been delivered. I called their customer service over 10 times, holding for as long as 30 mins on some calls, as soon as i'm the first one on the queue the call drops, i only got through when i called with a private number. The consultant that i spoke to was so rude and she told me to call the Pretoria branch, which i have been trying to call the whole day but the call also keeps getting dropped. I am so frustrated, who takes over a week to deliver a package in this day and age? Simply unacceptable, why have a customer service department if you actually not there to assist customers?@Woolworths stop using Fastway! Fastway you are pathetic, do better!
