Poor customer service received at Aramex Johannesburg together with Pick'n pay Woodmead

My sister sent a parcel from Pick'n pay Woodmead at Jhb via Aramex service. After a week I then called Aramex offices to trace it then I was asked to send my details. I was sent from pillar to post and mind you I'm the one that was calling them. It's now five months of calling and not getting my parcel back.I was asked to send the contents of the parcel, send the quotation and proof that indeed I used Aramex to send my things. I have been dealing Orrin Robinson who has been extremely rude to me and he couldn't assist, then the matter was transferred to Tesner Williams who also vanished on me, cause everytime I call it's either he's coming in late or unavailable. Then Thozama Madikane took over and asked that I send all the information that was requested by the previous guy's that I mentioned, after few days I was informed that the Risk Manager has denied the claim. I am extremely disappointed of this service if they can't compensate me they must give me back my goods.
