Where is my parcel

I am trying to locate a parcel sent from China. It left China on 28 January and I can't track its whereabouts since then. International tracking number: RG***CN sent to the following address: 1 Travertine Ave, N1 Business Park, Old Pretoria Main Rd, Centurion, 0157. I would like to find out where this parcel is and to which local post office it is to be delivered for me to collect.<br> <br>
