I expect this behavior to stop and also to be compensated.
I too was hit hard by this. Lost about half my investment and had to throw money at another rig to make up the slack. This rig should be de-listed immediately, huge fail rates and if what you're saying is true then it is no wonder the rig never even got close to the promised 1.33MH advertised.
All I can say is, hopefully someone considering renting this rig reads these comments. Caveat emptor.
