I just received a nice email from HashFast concerning my complaint. They assured me they are on the ball and trying to take care of this problem . They said people are getting refunds and that it is taking a while but it will happen . I did ask them to think about getting rid of that silly refund form to sign as that makes a person a little paranoid about things .
they told me they would give complete instructions for setting up the yoli evo boards if I took the upgrade offer . Which was a worry for me since I know nothing about this type of hardware .
Things are looking up with this response from them . I will be giving them some time to resolve the issue .
I certainly hope they are moving along in business as I think they have very talented people on the job and I would like to be checking out their stuff in the future as I think some asic instead of gpu equipment would be a great thing from them for mining them other types of coins which I own some of and would like to mine more but not with a gpu. Also their prices just can not be beat .
