THEMA: Reduced Balance

Hello, the message is for the purpose of notifying a problem, because the system has reduced my balance on two occasions with the pretext that I have removed the "Like" from a Facebook page when I do not remove anything. I think the problem may be that sometimes the FanSlave page directs me to Facebook pages that I already gave them "Like" and since I can not "like" it again, the system must detect a problem and reduce my overall balance . I hope you can solve my problem, since the system already removed 0.90 euros from my account and this can not continue happening, Thanks.
