Shocking service

I had a package sent to me with a valid tracking number BzUCCBN172626. The package was scanned in to the Durban office on 23 November and was never delivered. I have called several times' emailed several times and my queries are simply ignored. This is rude, unprofessional and unacceptable. They do not offer a free service. The contents of the package costed money. The loss is not simply going away.
