Hello, I'm the owner of beegcoin.com .
The problem has been resolved today. He can confirm.
Firstly, we doesn't receive mail. Probably a bug.
Secondly, quentiin thought he could withdraw bitcoins, or we're just a trading platform.
We send 50€ with Paypal.
In addition, we made a gesture of goodwill, and we offer 30€.
Sorry again.
Thank's.
