After waiting for very long time, about 2-3 months, I atleast have received my refund for my prospero x-3 trough wire payment. I can guarantee you guys, that minersource is trusted, safe and serious company and that they are issuing refunds, just you might have to wait, until you will get your money back. They sent me back every single penny. A big vouch for them

Hi did you manage to communicate your refund request with them?
I have never gotten through every time I tried to call them on their english number. I stayed late to adjust the time difference and call them during their working hours. It seems that no one picks up that number.
I'm considering refund now but I'm afraid I may not be able to communicate with them properly at all.
I mean to clarify, I'm pretty sure rokshis got his refund from Minersource, the US reseller.
People who have recently requested refunds from black arrow directly have been told "we cannot refund you because we've already started building the unit."
