I am sorry that I saw this too late - I too have been scammed by timetobit. 

Subscribed for their 1TH/s plan, and the payouts remain as 'pending'  with no response from support when emailed.

I then tried contacting them from another email id posing as a new customer who came across negative reviews on a forum and is anxious to join them, and they promptly responded that they have 'never wronged any customer' etc.. 

So somebody is THERE, but they just have set the bait and are waiting for people to fall in with their bitcoins.  I'm going to campaign against this scam, posting about them wherever I can.
