Parcel at customs since 08 December 2017

I have used Dpex to courier my stock from China to South Africa (East London) it has been showing that its at custom review since 08 Dec 2017. When I call, I am either put on hold till I drop the call or they tell me the same thing that my parcel is being processed for custom review. I have used Dpex before this occasion and custom clearance never take this long to be processed.

I am so annoyed and angry because I lost my parcel and no one is taking accountability for it. If you ask me, I will never use Dpex again from today onwards. I'd rather pay more on other courier companies than loose my valuable things.
