Hello I just registred to this forum beacuse of this situation!
I bought 2 shares about 1 week ago, I had a quick chat on skype with minershare because my shares don't show in my account and they told me that they were hacked but all was ok with data on the site and bitcoins was in cold storage.
I just checked the bitcoin address were i sent the coins and at the moment it shows the exact amount of my transaction (0.71 BTC)
Have you checked the addresses where you sent the coins?
Let me know something, I just thinking of a scam but I'm not 100% sure.....
