SkyNet Couriers - Terrible Service

I have a terrible experience with them. We have paid for our Vehicle Licence on the 7th December 2022 the parcel was collected and sent off to their Durban branch, which was received on the 8th December 2022 and I have tried numerous times to call them with no sucess. I have logged a query o their website and still nothing I have tried calling their Durban Branch, the number does not work. I have tried calling their Head Office also logged the complaint and still no word.

The parcel is still in their Durban Branch and we urgently need it before we can travel.

Should we receive a fine can we hold SkyNet responsible? They are deliberately delaying the parcel's delivery
