Poor Service from The Courier Guy

I booked the courier guy to pick up my parcel today waybill #WQNB9N. Before I booked the sender gave me go ahead since the order was ready to be picked up. To my surprise I received a message from courier guy saying that the parcel was not ready. I called the sender they were surprised because no one from courier guy went to attempt to collect the order. I then called courier guy to instruct the driver to go and pick up the parcel since the company was still open for the next 30min but the lady I was talking to by the name Cameron refused to assist I then requested to speak with the manager Nia he also refused to talk to me saying that I must send him a email. This is not my first time experiencing such issues with the courier Guy. And everytime Niaz refuses to attend to my complaints everything is in record and I will be happy to get the tracking report from the company if they went to pick up my order and I will apologize. I think it's now high time Mr Stephen Gleisner knows what is going on with the operations. I'm running a business and I loss because of unreliable service provider. Everytime I raise a complaint it fails on deaf ears. It's better to make my review published openly because I have heard enough of this treatment. My parcel was surpose to be delivered tomorrow. I don't know if I will get it tomorrow or I will have to lose another day again? I hope Niaz will be able to put his house in order otherwise Courier Guy will loose lots of money because of unprofessional leadership.
