I did an exchange of BTC > WMZ with xzzx.biz and now they are refusing to send money to me.

I did an exchange with XMLGOLD same day, same way BTC>WMZ and they completed no problem, I wish had used XMLGOLD for full amount but i found them after ( was looking for quick automatic exchange)

After searching here, it seems they ripped of other members too. They are somehow a trusted perfect money seller???

They refuse refund or send to my WMZ ID
