Last month, August 15, I bought 100 TH's Bitcoin Hashpower for $13,000.  The contract time for purchase expired with only 3 conformations.  I've logged in and emailed Genesis-Mining twice since the 15th concerning the expired purchase but have not received a reply or acknowledgement of my purchase or refund in my account with them.

I did receive acknowledgement from the person I used to get a 3% discount that said:

"We received your (my) form and the information match with a recent order that went through.  However since this was an order of more than 50 TH/s we will need to get the invoice issued by Genesis Mining."

I noticed today that Genesis-Mining no longer offers Bitcoin Hashpower for sale.  It appears to me that they've pocketed my funds and left me out in the cold. 

Any suggestions on how I can get a response and refund from Genesis-Mining?
