OK, so I contacted stocks.exchange support, and apart from saying that they would look into it, they have been absolutely unresponsive. Asking about the state of things is met with deafening silence. I created the support ticket on May 19th, today is June 2nd. My transaction is now 330 hours old, and has been confirmed 6447 times. I'm pretty sure the address was correct, since I copied the address from the exchange, and visually checked it. The CLI Dero wallet doesn't seem to show the addresses of the transactions, only the transaction IDs - so it's a bit hard to double check at this point.

Checking the wallet log, I saw this:

minimum fee 0.01624035 required fees 0.02436052 provided fee 0.00000000 size 15 fee/kb 0.00108269

Could this be related? I remember seeing that transactions may be stuck if the transaction fee was not paid. I don't recall being asked about paying a fee by the wallet client. Is there something I can do to fix this, if that's the problem?

Or, is it possible to cancel the transaction altogether, since it's currently stuck in limbo and nobody seem to want my goddamn money?

How can I proceed from here? Can anybody give any pointers? Point me in the direction of information that helps me solve the problem (if it's solvable at all)?
