You seem to completely miss the point. However, your last statement clearly suggest that you do get the point, and are just trying to weasel out of a legitimate request for a refund. The words "Perhaps there should be" says it all.
"Perhaps there should be a clarification somewhere that data token sales are final and no refunds will be granted at any time."
Your statement is exactly the point. As of today, 24 Aug 2020, the date of my request for a refund of the purchase price of data token, there is no clarification, or any documented statement at all, that token sales are final. All I have is your opinion, and you have no proof, no supporting documentation, and no written clarification to substantiate that opinion.
If you can just show me the written clarification/documentation to support your stance, this ordeal would be over. But, you can't. So, you continue to put up a false front to avoid an honorable settlement.
