I created a pretty cool twitter bot with the help of a friend (don't ask about it, i'm not selling it or showing it) and he got an email saying that this dude wanted to buy it. So I emailed him some screenshots of it and he liked it, so he bought it for 30$. Then right after, he "yelled" at me in all caps saying that it wasn't working and I am a scammer, he then opened up a dispute on paypal. So I tried to help him (for like 2 hours) trying to get it to work for him, he was telling me errors I have never heard of before. So then he demanded I refund him or he wouldn't remove the dispute. So after the refund he says, "oh, well it's working now, thanks. " then I spent forever trying to get him to pay me again, but he won't.. Now he's saying stuff like, HAHA i've already gave it to my friends and I'm gonna post it everywhere for people to use for free! Is there anything I can do on paypal, since he stole it and is now attempting to distribute it... Is there a dispute or case I could open? Thanks in advance.
