INTERNATIONAL PARCEL POST

I sent a parcel to Australia on 20 July. I have tracked this parcel on their website. It seems the parcel left on 24 July and since that date it has been "ON ROUTE". I have tried 20 or more times in the past two weeks to find out when it is expected to arrive. No-one answers the phones just ring and ring and finally you get cut off. I called head office and they gave me an alternative number. Number does not exist. I went into Gallo Manor Post Office and they could not give me any other information. They gave me another number and an email address. Same result no one answers phones or emails. I tried calling from 8.02am this morning same result. Finally this morning I went into Gallo Manor Post Office and spoke to Prisanah. I told her I want to claim on the insurance I took out. She said I need to get hold of International Customer Services to find out where my parcel is. I explained the situation to her. She told me to call 011. I said that is only dialing code for Johannesburg. She said that is the number I must call. I called while I stood there and surprise, surprise "This number does not exist". She made a photocopy of the insurance slip and said she would get back to me, this was 4 hours ago I have heard nothing and doubt very much that I ever will.

I AM DESPERATE TO KNOW WHERE MY PARCEL IS CAN SOMEONE PLEASE ASSIST ME.
