Disrespectful joke of a service

Having some experience in logistics myself, I am truly shocked that such cynical and spectacularly *********** levels of service are now just everyday business. They have made no attempt to deliver my parcel for THREE days in a row now and provided no courtesy feedback whatsoever. The WhatsApp platform, as well as the website chat box are just ticking-off exercises and in no way meant to assist customers. Even if you get past the bots by explicitly asking to speak to a human, the said human will just ignore whatever you have said up to that point and copy-paste the status from Track n Trace before IMMEDIATELY ending the conversation. No other contact details are published on the website. You can't even request to collect from the depot or instruct them to Return-To-Sender. If you look hard enough, you might get some cell phone numbers of people who will turn out to conveniently not be the ones responsible for your route on that day, but they will regurgitate that "it will be delivered Today". Basically, the ethos from the top - down is that they will deliver your stuff when they feel like and there is nothing you can do about it.
