Terrible customer service

I called the courier guy and gave the lady my tracking number as well as my company name and address, She then put me on hold for like 5 minutes. Then another person picks up, after I explain that I have been placed on hold they transfer me. I had to give the details again to a 3rd person who then told me the tracking number was wrong. I repeated the tracking number like 5 times and she finally tells me that the parcel will be delivered today. I ask them around what time because I gave them the work address and I will be knocking off soon, she then tells me that she cannot give me any special treatment and she cant tell me what time I can expect the parcel.
