Impossible to reach, service beyond Shocking!!!

I had a package shipped from china, after tracking it I saw that the package was sent to the wrong post office (my billing details have been the same as on many other successful deliveries) and then sent back to the Johannesburg international mail centre.<br> <br> I have literally more than 70 emails and made many more calls to all of the customer service number and held the ringing line until the call is dropped. I have not once gotten through or received a response. I do not know what I am to do?<br> The service is beyond shocking!!!!
