2 Parcels missing and no effort made to find it.

I ordered something from CNA online that was Dispatched on the 2nd of Dec 2015 with Dawn Wing. My parcels were shipped, as per the manifest when tracking the Waybill number, on the 3rd of December from PRY and arrived on 5 December 2015 at PLZ. After tracking my parcels, only 2 out of the 4 parcels actually physically arrived in Port Elizabeth, which were delivered on Monday, the 7th of December. <br> <br> 2 Parcels are still missing!! I have spoken to many people and no one seems to know whats happening! Marcel from the Port Elizabeth Depot has been EXCEPTIONALLY Helpful and seems to be the only one trying to do something. But this is COSTING me a fortune not having these parcels. <br> <br> I find it very unprofessional that the Waybill number tracks the Manifest and not the ACTUAL PHYSICAL parcel. I have not heard anything regarding these parcels since the 7th of December. Its been almost 2 weeks now since these parcels were Handed over to Dawnwing Couriers.<br> <br> I am growing very frustrated as my time is also very limited! Soon, excuses will be made like \We are closing for the holidays and we cant help you right now."I WANT MY PARCELS FOUND AND DELIVERED TO ME THIS WEEK"
