No customer service

I was told by agent on the 20th of Dec, if I book an overnight express and call in before 3pm the parcel would it picked collected and delivered the next day by 9am. I made my booking after 3 because the portal kept kicking me out. Thereafter I called and was told my parcel will be collected on the 21st and delivery will be the 22nd. It is now the 31st of December I have not received my package or any feedback as too when I will receive it. DSV call center agents have ZERO customer service! I spoke to many agents and eventually a team leader by Lulama Ngotsha who thought raising her voice and speaking over me would fix the problem so I asked to be escalated to her manager. After been on hold for over 20 minutes Nkhensani Rikhotso would pretended like he had no idea what was happening and made me explain the problem again. He offered no apology for the inconvenience or the pathetic behavior of his staff and to date he has not contacted me again with any update at all. DSV management are handled by people with very little or no customer service, professionalism and respect. DEFINITELY WILL NOT USE DSV AGAIN!!!
