I have my doubts about this. If this company has been around for a while then they must know that the first thing to have a great business is having great customer service. Someone here has requested a refund and it has been two weeks and he or she still have received it.
The second issue I have they don't accept debit or credit card as payment for the WTT or the buying the miners. Even thought they state you can pay in USD it has to be wire transfer. Just like coins once you send it it can't be taken back. I think you have 10- 30 minutes after sending a wire transfer to have the bank cancel it. And if you send your BTC or any other coin to them there will be nothing you will be able to do. With wire transfer you are responsible for making sure the money you are sending is to someone you trust or really want to send it to. What if you put 20k or 30 k into this business and something happens which causes you to take your money out or want to cancel for some other reason you probably wouldn't be able to do it.
I contacted them and they told me the reason they don't accept debit or credit card due to security reasons? do the mean that customers can file a complaint with their bank and request a refund and there is basically nothing they can do if the bank takes the money out of their account and give it back to the client, try doing that with wire transfer or coins.
