I sincerely feel like you complicating this or you may be prejudging, let me share why...
@essyk has done nice to track that delivery code, but you need to realize that they don't always use TNT, some times they have delivered to me via EMS, some times via Crazy weird companies..
Secondly, I want to disagree with you Otieno that it was stolen by Posta let me explain why.
There was a time they were supposed to deliver a package to me, i was not in Nairobi i had gone out for some holiday. The guy brought the package to where i lived and gave the guards at the gate the package. But they had to sign on some electronic machine and input the name. NOTE; it was delivered and the guard put the name "Mr XX".
When i went online it indicated delivered Name "Mr XX"
My Guess: This is what exactly happened to your package, it was delivered and the guy put the name on the electronic machine and promised to give you because he convince the carrier guys he knows you (probably at the office or werever.. ). The guy later realized he is holding something pricey na ni Njaanuary. This has happened severally, during delivery, i am 80% this could be the case and the guy Mwangi exists. Also when my small siblings ship in stuff through my parents Posta, the delivery always indicate the name of whoever picked up the parcel, not the owner of the parcel.
To be sincere i don't buy the storyline that Posta staff stole it. At first i always thought so when parcels delayed but over the years iv come to realize Posta rarely steal, my argument is purely that me, friends..colleagues have shipped so many flashy, petty, big, small things,(remember also customs opens) and nothing has ever dissapeared, my pals always use them, my sibbling shop on a monthly basis. NONE has ever been stolen by Posta.
Why not just load this cost with the lightinthebox and demand a reship, tell the chinese you dont know "Mwangi"
