"but due to sad past experience whereby after paying for expatriates travel
and immigration documents, they later change their minds towards the
job telling us they have gotten a better job offer somewhere".
Don't tell the scammers, but maybe if they didn't let everyone know that there are better deals around than the one they are offering they might have a better success rate!! I've seen idiots on TV who get roped into these scams, & I struggle to understand how anyone could be so naive.
P.S. - I have a baby Saquatch at home that I found in the bush after it's mother died. Unfortunately I can't afford to look after after it properly, but if you send me lots of money I'll let you name it!!
I wonder how homo sapiens became the dominant species on this rock.
