Have some telephone manners

I called the helpline ***. Earlier that morning to ask.where my unisa parcel was since I could see I had been tracking it since the 5th of Feb.I was told that according to the information it should be delivered today.so ok that's good but now it's 17:45 and nothing yet,so I call back the call center.and the lady said she didn't know what to do.so she would transfer me to the people who work with the driver.this rude man by the name of corneilous rudely tells me that his in a meeting g and that the parcel will get there.I mean really really.who does that,have some manners,this is a business,is that how you talk to your clients?
