Not going to disclose his secret hideout, but he does indeed work for vodacom, seen it myself
and no, his speedtest is unfortunately not a lie
Going a bit off topic here, I'm waiting for a parcel from the US at the moment. For those of you using USPS, just a heads up, their tracking takes quite a while to update, sometimes 2+ days, so don't panic if you don't see any activity.
Secondly, once the package arrives in SA, it is no longer tracked by USPS, as Ori said, you have to call the international mail center @ 0860 111 50 and give them your tracking no. They will then tell you whether the parcel has arrived in the country and if so, provide you with a local ii tracking no.
Be warned though, from personal experience I can tell you that a parcel can lay dormant at customs for 7+ days without being logged, resulting in you being told it isn't in country yet and you fearing the worst.
Customs can also take ages to clear your package, especially if there is no invoice attached (they will request one, which can easily add another week waiting time), the package is marked as a gift or the declared value seems too low. Also note that they can fine you for deliberately declaring a false value for the item (R1500 last time I checked), so watch out.
I can't stress enough how important it is to have tracking on any parcel ordered from overseas, if you go for services such as USPS Priority mail (which is untracked) prepare for a possible dose of nationalization
Lastly, if you can, try to avoid shipping to PO Boxes, as you'll have to deal with SAPO and possible further delays/damage/theft of your item. Courier if you can.
Pay the premium and rest easy.
