artists_beware | In need of help/advice

This is more of a premtive move on my part just in case something happens with this person later.

Its also me needing advice. I have offered to issue a refund but have not yet gotten a response.

This isnt a beware yet.

Several months ago I was commissioned by someone who shall remain anonymous, for now. I was doing an open stream card commission and he purchased a $10 ink with a $2 tip of a naked Ferret girl. I completed the card as he watched and it took me a week or so to mail it out. I honestly just wanted to wash my hands of him because the whole transaction had been borderline creepy and the guy seemed to treat women as objects  which, me being a girl, tends to rub me the wrong way.

So I sent it out, doing my ABSOLUTE BEST to write down his adress on the envelope. It was in french and absolutely full of accents and special characters. And sent it off with two other international orders.  Well I kept tabs on the other two internationals because I tend to befriend a GOOD amount of people out of country. One of which was a good friend and it took him over a month to get his cards, when they finally arrived I could breath a sigh of releif. So I assumed all had gone as planned and I completely forgot about the creepy guy.

Untill a week ago when he noted me on FA asking if I had sent out his card. Not remembering who he was, because I have done ALOT of cards between when i started and now I asked him to describe it. when he did I informed him I had indeed sent it and that if it hadn't arrived to check his local post office. I know in some international shipments that they hold things at the post for people to pick up, happens with my briton boyfriend all the time. I thought this was a reasonable thing to say as I know it happens fairly often and something may have just fallen through the cracks.

The response I got was... well.. a tad rude. (i cant say i didnt respond any better but alas it was 3am and I was in a less than accomodating mood.)

My first response when he told me he didnt receive it:

His reply:

which incited this reply from me.

I tried to remain professional, I did. But I was a little ticked off at the idea he implyed I was trying to scam him.

I havent yet gotten a reply but I'd really like to know what to do so this doesn't happen in the future.

I also have this sneaking suspicion he's trying to get something for nothing but seeing as I cant prove he didnt get the card I'm up a creek. Its only $10 but this is quite literally MONTHS after the fact I would have thought he'd have brought this up alot sooner.
EDIT: I have spoken to him and implored him to check his local post office. He's currently working in Paris and his mother is still at his old adress so hes going to ask her to check. More updates when I know more.

On another note we resolved the rudeness issue on both our parts, I apologised for my reaction to his reply and he inturn apologised for his bluntness. So I can at least account for the issue with the customer to be resolved, the shipping issue is still pending though.
