Fair Forex

When transferring money to Fair Forex using Bitcoin, Fair Forex gives you their address and QR code to scan. I scanned the code with my BTC wallet. My wallet stated and showed the transaction approved and completed. However, my Fair Forex account did not show the deposit. I waited days to give it some time, still nothing. I contacted them about the issue. They stated I should have taken a picture of the transaction and sent it to them. I sent the pics of the transaction, the date, the time, the address the money was sent from and the amount. After I sent them the info they requested; They said they could not find the money and the money amount I sent them could have changed due to ‘fees’... I have never heard of this. Also, no other broker has ever asked for pics of sending money, especially when the broker is giving you the actual address to send the money (scan code). It makes no sense. Any how they can’t find the money sent for some odd reason. So it’s supposedly lost in cyber space. Seems a bit shaky to me.
