sorry to hear of your bad luck ;its a wake up call for people like myself who almost take it for granted all deals on here will have a happy ending.
im hoping you weren't dealing with any long standing "mem" which is my first criteria unless they are paying me in the first instance.
there's been some well publicised dodgey dealings on other sights which has put them to temporary flight but unfortunately the "hyenas"
that scavenge off honest folk have a low cunning that enables them to camouflage their ID ;but track record goes a long way in this situation.
hope you have some kind of come back on this other than knowing the "hyenas" are in the minority.
