I cant track parcel sent to UK over a month ago

I sent out my parcel to London on 8th April - i got messages to say in had arrived in Durban at the outward exchange office and then again that it had departed from the outward exchange office on the 17th April - i have tried to track it since then and it shows zero change or the website just shows an error message - i have tried emailing as well as the sms service you have on offer to no avail - the customer service line keeps me on hold for 30mins and then just cuts off - i would really appreciate help in finding out when my parcel will arrive in the UK and if it is on hold in Durban is there any way i can get it back so i can send it in a more reliable manner.<br> <br> I have put in the tracking nr below in the acc/policy section of this mail.<br> <br> Thank-you.
