Bad customer experience

the parcel was supposed to be delivered at my business address, when i saw the time the business was about to close and i decided to call and track the parcel, i obviously spent more than minutes on the line waiting for someone to pick which they eventually did, and i was transferred to the reception, which transferred me back to the customer service. Lerato managed to assist me by telling with whom is my parcel, she called him and we spoke. his attitude is very bad for someone that has missed a delivery, he is around centurion and wants me to stay somewhere and call him at 17h00 to find out where he is. when i told him i won't be able to do that he must come and drop my things before 17h00, he tells me i can get them tomorrow or get my refund back from where i bought them. obviously i will ask USN to consider another courier company, and maybe when i cancel the order because it didn't get to me on time, that will motivate them to look elsewhere, where customer service will be better.
