[jeppe11887]

Hi, This is my first time using this, I saw a serie a few months ago and i wonder what name it is, Its about some people that are " fooling people" like saying to a rich man(that has done something to them) that he can make a great deal if he invest 500 pounds in our fond, and u will earm 1500 if you dont earn it you will get 500 back. Thats just an example of what its like, So Its in England ( U.K ) And its one " Black coloured man in it, One Woman, One English guy a big English accsent, And A Old man, And a Asian ( not 100% about the Asian), I might forgot some one,
So Thats what I remember please tell me if you know what serie that is,
I might give a reward to the person that knows what serie it is and tells me it,
Regards!
