Same problem with Gigawatt with us as well. Our miners became operational after 2-months of delay (an eternity in this field) with 15% of the miners mysteriously being under "repair." After one week, 20% of our miners are now under "repair."
My guess is that they do not have the space to host all the miners and coins they sold, so they are running a complicated Ponzi scheme to decommission miners already operational to give to the new suckers they've convinced to buy into their shill. The reason for little to no response from customer support is because their staff likely are quitting already sinking ship.
The delays are likely due to monumental incompetence, rather than fraud, but if there is a class action lawsuit, we would gladly join.
