SP-Tech is the best in hosting service and miners. I don't get why you would want a refund.
Guy or Katya has always answered my emails within 10 minutes or less, even if it's like zero-dark thirty in Israel. I don't know if they ever sleep at all.
Not sure what you did to piss him off but it shows when he doesn't reply to you that fast. Be courteous.
I don't deny that they are. Cannot complain about the products.
It was Barbara not Katya. Katya tended to reply quite quick. At some point I was getting responses from them both so things got mixed up a bit.
Also, I transfered only 90% of the total amount for the purchase because I got messed up currency conversion. Just before I transfered remaining amount I was told that SP31s are out of stock so I can replace it with SP35. I asked for the refund and cancelled my hosting plan (not with S-T). Then I received an e-mail that they have got SP31 in stock again.
Anyway, here iI explained what happened:
