It also says the prise will be released through our agent called dr. Douglas deo. On september 25/2019 the mentioned diplomat come to my country ethiopia and called on my phone. He said pay the 14500 ethiopian birr for custom clearance charge. I successfully paid it. Later he asked me to be certified for antiterrerist clearance and requested me to pay 34, 400 ethiopian birr for it. Finally he told me that my prise money is being released to your account via national bank of ethiopia. Also he forwarded me an email message that i s sent by national bank of ethiopia. The message says 80% of your money is transfered and20% is on hold because the operation is failed for you have not paid tax and got tax payment code.
