I just received the same offer. Back when I bought the contract (May 2014), 10 large for 2.2 Th/s for 1 year, it was performing nicely until August or so. received about 7 btc in 4 months, which would of been fine, had the payouts remained the same, or the price of bitcoin stayed above 500. The main thing was that Abiodun had promised an increase to 8+ Ph/s by December. Instead it DROPPED from 4.4 Ph/s when I bought the contract to where it is now- 1.7 Ph/s.
Good thing is I live in Austin, TX, where I went to Cloudhashing's physical office to purchase my contract. I will be going to pay them a visit today or tomorrow.
