Greetings
I'm a member of bitminer.io,  I made a withdrawal of 0.0008btc as a free member, the amount was deducted from my balance but it has not reflected in my block chain account. This happened last week.  A day afterwards or more I upgraded to V1.1 and to my greatest surprise,  I logged in to my bit miner.io office this morning to see a negative balance of 0.12....btc
Can somebody please explain to me what is happening?
