Between me and my wife's accounts, we have had 1 successful buy out of 3.
My first order was cancelled and support threw the TOS in my face.
My wife's first order went. Second was cancelled AFTER the promised fulfillment date. We've started contacting support. Depending on the response, I may be interested in getting a form of legal mediation going. So far the TOS is full of contradictions from actual practices.
We've had similar experience. 1 of 3 transactions made it through. The other 2 were cancelled when the price of BTC moved against them when the fulfilment date came around. Funny that. No point in doing business with them.
Out of curiosity, do they cancel transactions if BTC price drops? Would be convenient on their part.
