Courier Guy= no delivery

Seems as if most of the reviews of courier guy has been bad. It unfortunate that i have to add to list of complaining customer but I have completely lost faith in the courier guy. This is the second time that a service provider has used there service to deliver my order and everytime is a mess up. I was told by my supplier that i would received my order between the 3-5th of June 2020. I am still awaiting.After phone around 20 times i finally go some information, I was told that i might get my delivery by tomorrow ( just to emphasis i paid for my courier) it was not a free service offered.The fact that service providers can give such bad service in today's fast past world is sad.I hope that someone can actually tell me when I will be getting my order
