I actually always make contact with them, send them emails etc, then when it comes to it, I ask for their credit card details, number security strip number and pin number.
I never get the pin but wont stop trying to rob some scamming African on the odd occasion as we have cc processing, maybe one day they will slip up and actually send the money by mistake.
had a couple of phone calls off them too which ended up being amusing. :lol1:
