Bad service and feedback on parcel

I went to the post office at Benmore shopping centre on 25 March 2015 to courier a parcel (a wedding dress) to China which I paid R500 for. They told me this would be delivered within a week. The tracking number is CN***ZA. Now after 3 weeks, I am trying to locate my parcel. As per the website, I have sent a sms to track my parcel, but no response, I sent an email to Phuthuma Gcingca [Email Removed] which told me I need to contact ***or ***. There was no answer on the 011 number and after a couple of minutes the call just ends. This happened on numerous occasions. When I called the 0860 number, I was holding for over 40 minutes, then when my call finally got answered, the lady told me that my parcel left the country on 27 March 2015 but she cannot tell me whether it arrived in China as the system cannot pick it up. When I asked her how it is possible that I am paying them for a service and she cannot tell me where my parcel is, she hung up. I have even sent an email to Head Office....no response.<br> <br> This is shocking service. I urgently require feedback on my parcel and whether it reached the destination.
