I am sorry for your bad experience. I hope either Mistertango or BTC-exchange.com come up with a justifiable response. Though I believe you cannot just receive transfers from anonymous people.
I just got verified with Mistertango and shot some email to see what documents they may need for incoming wire transfers because I deposit my money through a financial institution. I wish they are more clear about what documents they need for incoming transfers. That makes it much easier.
Also, it would be nice if they offer a VIP/Premium plan. I do not mind pay more to get better support. Right now it's been a few days that I got verified but cannot open the application because I do not receive sms verification code (I am in Canada) I emailed them, they said they fixed the sms issue and asked me to try again. I tried again but same problem!
