Buffalo Logistics agent rude and arrogant

I called the call centre and a guy named Sbu or Mdu answered, very poor audio. I did tell him that I would like to know if my parcel is getting delivered today as their tracking states received in South Africa yesterday. I let him know I will not be home the next few days therefore I was concerned about delivery as my order was paid for. He was so rude and arrogant. As if he is doing me a favor! He gave me the same info that is on the app, no help at all. Terrible service! Teach your agents how to interact with clients. They have zero customer service skills.
