Poor Service Delivery from the Courier Guy

I booked a parcel for collection and delivery with The Courier Guy on the 8th of March. The trip is 2 hours outside of JHB and normally takes 2 days for parcels to reach us. The parcel was booked and insurance taken out on the parcel as well as it is expensive and fragile, with the correct delivery address added to the booking, with postal code. Upon tracking my parcel on the track and trace, The Courier Guy in JHB decided to send my parcel all the way to CPT, making my insurance cover on the parcel null and void, as it only covered a specific router for 3 days. Today 12 days has passed and I still have not received my parcel that normally takes 2 days for a 2 hour trip, and the online track and trace system has not been updated since the 16th of March. Very poor service from The Courier Guy in general. I won't trust them with my next high value parcel to be delivered on time. Support is also useless in providing any answers as they have been contacted many times.
