I was able to finally get through to Martin, looks emails not getting through from the ISP I think, possibly blocked.
iSpace has a policy that unclaimed coins are donated to the pool after weeks... as I wasn't reaching the minimum threshold, the balance was being donated to the pool!
Apparently he's adjusting the minimum payout threshold to prevent this happening again.
I to have had problems but no one is getting back to me
Did you read the process on how he got hold of the owner? How are you reaching them by the way? Its clear that hey mentioned that he's email was not getting through because of a possible ISP block. And then @franky1, gave the official twitter account of the owner and that's how the OP have reached sadly though he didn't reach the minimum threshold so as per policy of iSpace it was donated to the pool. I suggest that you go on that route as well and maybe they will respond to your issues. Goodluck to you.
