Cannot find my parcel

I tried to send a parcel in July 2015 but it was returned as it was only for documents and I tried to send a T-Shirt for my Son (my mistake) I then resent the stuff with another envelope. I was given the old tracking slip with a new envelope and told to keep it for documents. I sent my Sons matric certificates to him on the 18-02-2016 with the old tracking number. I was not able to keep a copy as I had to put it in the envelope. The parcel has not arrived at my Son yet and when I enquire I am told they cannot help me without the tracking number which I do not have BUT there is no receord of a parcel being sent to the UK in that week which is impossible. My husband has obtained the camera footage of him depositing the envelope into the Aramax box. I have also been told by Aramax that I should not have used the old tracking number BUT I only did what they told me to do. It is too easy for them to just reply that there is nothing they can do. How is this possible they must have some kind of recording system a big company like this. I have contacted the boss Hein at Head Office but apparently he doesn't take calls so I am waiting for him to contact me HOW CAN HE NOT TAKE CALLS!!!!!!<br> <br>
