Although I cannot remember doing anything, I have received an e mail telling me that "following our secret agreement, they have sent me a packing case full of money". They tell me that the case is marked as "diplomatic papers" and I am not to tell anyone that it is money.
The case weighs 420 Kg but they have lied and only paid for 270Kg at $5700.
They gave me a UK telephone number of the Diplomatic Courier Services if I wanted to progress the package.
I couldn't see what the scam was initially but I eventually realised that, if I called the number, they would probably confirm that they had the package and tell me that there was another $5700 to pay for shipping. Oh yea? Delete!!!
