Parcels via Canada?RB976348651CN and RB914077168CN both show last scanned destination as "CAN" which I am assuming is CANADA.

I have to parcels coming from China, destined for South Africa.
Why would the parcels go via Canada to South Africa? They have also been at this location for quite a number of days already. I have spoken to our countries incoming mail centre, and they assure me that they haven't arrived in SA yet.
Anyone that can help?
