There's definitely something wrong, my payments went from 0.02something to 0.015 yesterday and 0.012 today. I have logged a call.
Okay Guys i have the same Problem as u aswell. I heard about lowering the Fees per gh/s from CryptoMiningblog.
That is only for new contracts purchased since September 16th 2015. Any contracts before have not had any maintenance fee changes.
