Here's the answer Coinpayments.net to my request for a refund.
Dear...
When visiting your deposits page you are provided with the warning message that you must include the Destination Tag/Payment ID/Memo/Message when depositing to your account. We try our best, but not every recovery attempt can be successful due to technical limitations, and exhausting manpower utilization options. Upon successful recovery, a fee of 8% will be deducted before depositing the recovered coins into your account.
We view protection of users' privacy as a very important principle, but to proceed with a recovery, you must provide additional information to identify yourself.
If you object to your information being transferred or used in this way, please disregard this request, and do not reply to this ticket to acknowledge the terms and disagree to a coin recovery attempt.
Otherwise if you agree, proceed to complete KYC at
