Lucky for you, I invested in Hashflare, they have never answered any ticket; for over a year now.
My btc has been in their wallet for over a year.   Cannot buy any GH/s cannot withdraw my BTC.
They have refused to answer any ticket since last year.   TOTAL RIP-OFF

They withdrew my BTC, I cannot withdraw because their site shows me I have zero balance.
