Holding back parcels unnecessary

I am very much upset as I write this report.i know that it will probably fall into deaf ears like my many phone calls to the south african postal parcels customs. However I will try, I was sent through an item on the19 of November 2015 which supposedly arrived in south africa on the8th of January 2016 and has been laying there till today.i was told that customs were on strike which could be the cause for the delay however what angers me is that I have since then received parcel also items of clothing which were posted end of November and beginning of December,which I presume would have also went through to customs.why have these been released and why is item still laying there.if I need to pay custom fees then I should be notified but however I have been trying to phone some dead end number to no avail which is forever supossedly busy.***.i had previously dialled 011961?6077 and spoken to Skhumbuzo who referred me to the number that never works.i honestly fail to see how I can receive items that we posted late earlier then the one posted early.what is it still doing in customs?tracking number.RC***MY?
