Hi, there! So I bought a horse that needed some TLC and groceries for $100. He was a stallion at the time, and they agreed to let me keep him on their property until I got him castrated. I went up there frequently to love on him and work on his ground manners (the previous owners had requested that I didn't ride him on their property until he was castrated). I took a bag of feed and dewormer to the place he was for them to text me and tell me that I needed to come get the feed, that it wasn't right. (my horse, I believe I'll feed him what I like) Then they tried telling me I owed them money for feed and hay and CASTRATION. They castrated my horse without my permission by someone who isn't a licensed vet. And want me to pay for it! My horse shares the pasture with his colt, who is their horse, and they shared feed and hay. I told them I'd pay half because he was sharing with his son. They then informed me that they administered shots and antibiotics themselves (also without my permission), claiming that they knew what they were doing because they worked in a vet's office for years and were "pretty sure" he couldn't overdose on Penacillian! I'm a minor, so I also had my mom sign the bill of sale, although they're trying to tell me it isn't valid. They won't give my horse unless I pay them their "desired" amount, even though I feel like I owe them nothing. Can't even give me receipts. They're coming up with every response in the book, that it's not valid because I'm not 18 (they knew my age and still accepted the money, and my mom signed it also), I owe them, etc. They even threatened to press charges on me for trespassing! Please help, TIA!
