I was scammed / lied to by a ‘fan’ and now I’m trying to find out how to get my money back

I don’t wanna make this super long, because I’m sure I’m not the only one who this has happened to.

Someone I met in person at the iHeart festival in Vegas when The Weeknd performed for the very first time in September 24’ after his last tour, who I maintained acquaintance level contact with up to this point, said that they were able to acquire The Weeknd Nespresso bundle, and told me they could get me a set if I wanted one. They showed me photos of them obtaining this set, but their story changed almost immediately, saying they would have to do some work to get more since they already have people they were going to give them to, but they told me they would get me one. After some discussion, we agreed on a price, and after that basically nothing.

Three months have gone by and in all my attempts, I’ve had little to no response after the first month, and when I got a hold of them recently, maybe a month ago, I was told there was shipping issues and they were filing a claim. Since then, no updates after all my attempts to reach out even asking to get my money back. Now I’m at an impasse, because I have these receipts that show they have taken my money, but since I’m not hearing from them, I’m trying to be polite and not out them everywhere I can online. But then again the other part of me says, screw it, they made this choice on their own, so I can’t feel bad for them any longer

I’m not a spiteful or mean person, i’m just tired of being taken advantage of, especially when people find something meaningful to a human being and take advantage of that

I’m able to send receipts from this person to their family, because at this point I can’t feel bad any longer that this family raised a crook and a thief. But I’m not sure what to do.

On top of that, I feel that this person should pay me back interest since they’ve had my money and never followed through on their promise. I may not get anything, but I’m looking for advice at all on how to handle the situation because, I’ve already posted a countdown for this person to respond, and by this time tomorrow, I’ll have sent receipts to as many people as I can, as well as posting online.

On top of that, I know their employer and used to work for the same employer, so I don’t know if that’s a way to approach it either.

Looking for advice, feedback, if anyone wants to message me directly that’s cool, I’m even open to talking on the phone because truthfully, I so better with verbal communication.
