As has been mentioned here several times, before a service can and may be labelled as scam, you should first provide solid evidence!
Otherwise it can quickly happen that you are been branded for defamation.
Apart from that, I think that you should first contact the support...

It is not unusual that the OP is not active here on Bitcointalk.
The activities on Bitcointalk are carried out by others.
In this case: yahoo62278.

At Roobet.com, for example, the OP is also not active, because Hhampuz takes care of the forum promo on behalf of Roobet.
