Just so you know guys, i sent an email to centra tech support asking questions regarding a refund from the same address that i singed up on their site, like an hour ago and they have never replied back negative or positive. So i decided to sent them another email from a different address asking about buying tokens in the sale. In this email they replied in like 5 mins and they also mentioned that the have a 25% extra bonus.
I see that CentraTech replied in this thread saying that no refund will be made. I can't say that i am 100% sure that this is a SCAM, but all these seem pretty shady.
I hope everything turns out good.
