I'm currently in a back and forth with a commissioner over a refund (no names of course.)
The issue being between the time of the commission and the time it was completed I had several irl events that eventually resulted in the temporary loss of access tot he account. Eventually I had a friend log into my account for me to upload art, reply to PMs, and help me get a huge mess sorted out.
With this particular commission, the commissioner was claiming I owed them for two pieces of work, one finished and one not finished and that they had sent me a note before I uploaded the commission. I told them that since I could not find a PM in my inbox, they hadn't replied to my refund journal, and my friend never saw the notice wanting a refund until a new message in my inbox a month after I uploaded the commission, I would refund them only one of the pieces.
I had asked them for a screen cap of the note, which they said they would provide, and then I didn't hear from them again until now. I asked for proof again, but they didn't provide it, so I just refunded them the larger half of the payment for the second commission that was never done.
They replied again, this time arguing my refund and requesting the full one and I asked them to refer to the previous notes as to why only one was refunded. They then replied back, finally, with a screen cap of the note.
I have no record of this note at all. Not in my outbox, not in my inbox, any folders, archives, or trash. My friend who was managing the account at the time hadn't seen it either.
I'm honestly at a loss for what to do.
Also, as a test, my friend came up with the idea of typing in the message number screencap into the address bar. When we type in the screencap the commissioner gave us, it says error.

My friend and I did a test where I sent her a message and both deleted them completely, even out of the trash, and it still shows up on both our ends with the address url, so she believes it is possible to be faked.
I'm more than happy to refund the commissioner if I am truly in the wrong, but taking everything into consideration, I'm not sure who is right?
I'd love any advice as to what the cause of the missing message would be!
Just to be sure 100%, since the forensics is questionable/debatable, I am sending the screencap/PM url to an admin to see if they can confirm if it is real or not.
