Thank you all for your replies. I will contact Coinbase today, and keep doing so to try to convince them.
I will devinitely keep you all updated.
Keep in touch with them if there is any way to recover funds. I once sent a token to coinbase that was not listed on coinbase, since the amount of funds was small so I did not contact them anymore and did not recover my fund. So far that token has not been listed on coinbase so I don't see any other way to get my that fund back. You keep try to find a way to recover your funds.
