******* at the SA Post Office

I'm sure that individuals who have had the misfortune of having to use this service will not be taken aback by my nasty suspicion. I honestly can't make out what's happened to my 22 December post to a supplier. My conclusion is that clearly someone at the SA Post Office must have helped him/herself to it. :( I posted my parcel on the 21st of December at the Randburg branch and it arrived at the Germinston he next day at 18:13:00. I was told that delivery would take 5 days. ''Parcel is still in transit.'' I expected a delay because it was posted over the holiday, but it's been too long for me not to raise an eyebrow. Someone from SAPO please explain what's going on?
