I have bought the 1 Month Tier 4 package for 25$ via BTC (big big mistake!) turns out these a****s are a scam. I have previously inquired to the online chat about billing and had an answer instantly, now when I am trying to get their product to work or get a refund I didn't get an answer all 5 times. The service simply doesn't work, it's complete sh*t, please refrain from making the same mistake I did. F**k them and f**k all you scammers endorsing their products as well.
