Jabita Hotel: Jazz Of Fraudsters

I recently got duped when I tried to change some dollars at Jabita Hotel, Ikeja. I counted the money while there with my sister and friend, it was 99pieces in a pack. The guy added one more piece, making 100.
On getting to where I needed to use the money, it was less by 31,000. They DUPED ME!!! My fear is was it jazz they used or what? I'm still too scared to carry the bag till today.

@ poster,
 so sorry about your ordeal, but like they say, in Nigeria, you got to be on your toes.Well here is how it works. For me sometimes when in Nigeria, I have over 5 to 9 thousand dollars to change at a time. This is how I do it.
   Call the mallam to meet me at the bank, I count my dollars, give it to the cashier, he counts his naira gives it to my cashier, who counts verify and then puts it right into my Nigerian account, then hand the mallam the agreed dollar amount.

This is what I'm guessing happened to you-its no jazz-they counted the money short of a piece. Then the asked you to count. You counted and it was short of a piece. Then, they feigned ignorance like the less one piece was a mistake,as such they need to verify it. You gave it back to them, they counted, removed a few more pieces and agreed that it was missing one piece. This ONE piece they would add to it before your eyes.Little would you realize that, in lieu of ONE piece, they had removed THREE or more pieces. Now, because you already counted the money and here ONE piece is added, you never bothered to recount. ITS THE DOCTRINE OF THE MORE YOU LOOK THE LESS YOU SEE. please be careful next time.
