... Even though i would consider hash flare a very dodgy business anyways, are you sure that your bitcoin transaction was sent to the right address?
I use extreme caution when copying the receive address and making a BTC transfer. I checked it over more than once before sending it. It is the correct receive address that went to Hashflare, and the BTC is now in their possession.
It has now been 9 days and I have had zero response from Hashflare .. so far this is a theft.
