While it is true that this kind of thing could happen anywhere it's just more likely with a Nigerian company - if you leave the buggers an opening they will screw you. Unless you have actually done business there over a period then you have absolutely no idea of how deep the culture of corruption is embedded in Nigerian society.As an example I saw the national oil company building ablaze from end to end the morning after the government announced a new corruption inquiry - could not be extinguished because ' hoses could not reach'.The Abacha family by most estimates stole 6 billion dollars of oil revenue.If you are into crime,corruption and squalor,You will love the place.
