If its from POSLAJU or any other famous shipment company such as Gedex , you'll get a tracking number which you can track the progress of your shipment

Your question wasn't clear at all. I made the assumption that you don't trust the delivery boy from a courier company. In this case he's a dispatch boy , and hes not from a courier company (since you have said no tracking numbers would be given). Its like this , I have a business and I ask my brother to deliver out the items for me , he becomes my dispatch boy

I do hope that is what you mean
