I would like a refund for the bogus Hashfast card you sent me as a replacement for the pre-order. The card ran at 30% hash rate for 12 hours giving me a whopping $.02btc before dying. I've tried several times to contact you in writing and VM. I still have the bad card post marked 4 days after receiving it because it was unclaimed at the address posted on your website. Sending me an experimental board without a warranty doesn't count as making good on my purchase. I have all of this documented and provable. Are you going to refund ME Ken?

This is an ongoing problem, MtGox has been telling me the funds from a transaction will be refunded automatically for three months now. When I look at the address I sent my funds to it shows a $0 balance but the funds moved out of that address within a couple hours of sending it. The vendor never received the funds  MtGox I says the purchase was cancelled and will be refunded "soon". Anybody know a way to escalate this to resolve it?

I tried a bunch of different searches and see very little on settings for queue, scantime and expiry. Does it depend on hashrate and very from machine to machine? Can someone please help explain?
