I tried buying 1000$ worth of dimcoin with bitcoin using coinmama/coinpayments yesterday and got this email today.
Your payment of 0.36044000 BTC to DIMCOIN ICO has timed out without us receiving the required funds.
The transaction with ID CPBG37SZ3MYAHNFOWESMY94XFE has been cancelled.
If you sent funds that didn't confirm in time to complete the transaction, they will still need to confirmation on the blockchain before we can return them to you. Only after it has been confirmed on the blockchain will you receive an email within 8 hours with a link to claim the refund.
If you don't receive the email 8 hours AFTER getting confirmations or need any help or assistance feel free to contact us at

Coinpayments have clarified that I must have double clicked and there were 2 payments. Then the way gmail clusters mail in a thread... I missed the email of successful transaction.
