Bad customer service and no telephone manners

I am very disappointed with the level of treatment the staff at Courier IT conducts themselves. It as if they are God greatest gifts with their stingy bad attitude and service delivery. I have been waiting for a parcel to be delivered to me for over a month. Firstly no notification or arrangement was made to say that the parcel will be delivered when? If I will be available on that day or not. Then on Thursday morning at around 09h22 I got a call from our company receptionists informing me that there is a delivery for me at reception. I advised her that I am not at work but I'm around the suburb and that it will take me 5 minutes to come pick up the parcel and she advised the delivery guy. To my surprise after 5 minutes I got another call from our receptionists saying the guy said he can deliver the parcel to where I was since I mentioned that I was not far, I gave him the address of where I was and he never pitched, later that afternoon got an sms to notify me to arrange for my parcel to be delivered from courier IT. Fast forward to this morning 03.04.2018 I then called courier IT to arrange and to my surprise the first person was rude and hanged up the phone. Called back spoke to some guy and he was not much of help, I gave him the waybill of the parcel and he said he cannot pick it up. I asked him how? because the parcel was being shipped to my workplace, so he cannot say that the parcel is not reflecting on their system. I told him my dissatisfaction with their bad service and he got aggravated and defensive on the line and then hanged up the phone on my ear.
