It's a shame I did not look them up on this forum before the exchange, as I would have seen all the others that they stole from.
Unfortunately a huge number of people do not conduct any research when they are about to use an exchange. FixedFloat has an extremely bad reputation, they are being labelled as scammers by some of those that have used their services. If you carried out some research I am sure you would have saved yourself from the hassle.
How ironic given that they just harvested all of my very real and legitimate personal information, in addition to my very legally obtained BTC.
They seem to have made a decision to scam you and asked for your personal details in the hope you would decline to send it. After you met all of their requirements, they had no reason to not release the exchanged funds. Now they have your personal details, they are in a position to sell it to criminals if they choose to.
