I had the same issue too. It was on the 8th January where I purchased the 12600 mcoins and didn't receive the mcoins. Since signs of imperishability was on sale that day, I didn't want to lose the discount. So I purchased another 12600 mcoins and I received the mcoins, for the second purchase. Until now, I still haven't received the mcoins for the first purchase. I've already reported this issue to the Support section of warspear website. Still waiting for their response. Although, I just want them to refund for the first payment since I've got my mcoins from the second purchase.
