I filed a complain ticket and they basically said no decision made if any compensation will be given for selling u this brick.
They are trying to sweep it under the carpet...
To be fair, it WAS a gamble from the get go. Unless they knew the coin would tank (which, keep in mind, ALL crypto is pretty low at the moment) and/or they knew that GPUs were capable of more and would eventually outpace the miner, they didn't actually do anything wrong.
Gambling on a new machine designed for one specific (and NEW) coin is, well, a gamble. You don't get pissed at the casino when you roll craps, unless they loaded the dice.
