Bad service

Dsv sent me a notification on the 26th of March 2021,regarding my parcel that it will take 1-6 days to be delivered and it was never delivered. I've started calling DSV customer service on the 31th to track my delivery, I was told it was scanned out if I don't receive it on that day I should expect from the 5th of April due to public holidays Tintswalo was assisting me. Therefore I waited until the 5th on this day between 16:00 - 16:30 I called DSV again to track my parcel I was told my parcel its with the driver probably it will be delivered cause they work until 18:00 due to high volume of work.. I asked for the contact number for the driver I was told the is none on the system.on the 09th I called dsv customer care I spoke to Tintswalo I wanted to find out why I'm not receiving my delivery, I wanted the name of the driver who was having my parcel, I was told it was with Thabang Sebophona, my parcel was sent back to warehouse, I didn't receive any communication from anyone, I kept on checking my unisa email but the was no messages,I kept on phoning customer service but I'm not getting my parcel . I'm extremely disappointed and not happy with your services, it's unacceptable for a customer to keep on asking for your services and it's not even rendered. management of this company is nowhere to be found..I need correspondence regarding this matter.10 working days now, Dsv is keeping my parcel
