I have troubles with coinchanges.net website for crypto exchange. A month ago I found it and wanted to trade my ETH for BTC. I deposited 0.07 ETH and they blocked it claiming it is suspicious transaction or whatever. I did not think that people could be so cruel.

It has been a month and they refuse to return my funds back to my address. They said "we are investigating". I mean they are not there to investigate, they must refund the user if user requests that one. They deceived me.
