Cannot reach anyone for feedback

I purchased an item overseas and got a call (05/05/15)from a lady requesting an invoice in order for item to be released. I sent confirmation of payment to Buzeka Mda as instructed (as I do not have invoice), asking if this would be sufficient. I have not heard from anyone since and do not get through to anyone when I call the track and trace call centre or any of the numbers listed on the website. Tracking information on the parcel has not been updated since 21/04/15. What is going on??? Where is my parcel??? Am I going to get it???
