Basically a scam... they take the real money from you with promises of a firm timeframe of delivery of your gold, then delay after delay, excuses after excuses...
In the end, real money out of your pocket and no delivery of anything, even though they make you do "this and that" like placing items on neutral auction house, placing another item on horde/alliance auction house etc etc...
DO NOT WASTE TIME AND MONEY on these scammers.
