Incorrect route pathetic service

I am waiting on urgent NATIS documents sent by Wesbank via DSV. It is already 11 days after it has been sent. Still I have not received my package. I called DSV three time already only to hear the same excuse every time. "The package has been incorrectly sent on the wrong route. I tried to call DSV'S radio centre in Cape Town on two landline numbers, but the phone just keeps ringing.

How difficult can it be to send a parcel to the correct route?

Absolutely disgusted in this pathetic service!
