I sent XMR in two transaction attempts to an exchange that required the purchase be funded within 3 hours.
For some reason, even though I had smaller previous transactions go through successfully, these did not.
The recipient says my transaction id is not in their system.
One of them looks fully completed in XMRchain.net. The other shows up in my wallet's transaction list as "unidentified recipient".
In either case, they don't have the money and neither do I. This was 5 days ago. When I look up the transaction id, the confirmations are in the 4000s.
How do I get the funds back?
