Help us get Twinkie back!!!

We need your help! Twinkie a horse that we have known forever is in a bad situation. A friend sold him to a couple as a light riding horse. The buyer signed a first right refusal contract, for two months he was doing okay. While i was scrolling through facebook i saw an ad about a 14 yr old aqha gelding for sale as a reining horse. The owners were trying to sell him as a reining horse, even though when he slides or spins he goes lame. Due to a torn imparligament that makes him a trail horse or a light riding horse. His old owner contacted him back asking for him back and the lady ignored all the calls and texts. She finally answerd and said you can have him, i need 1,000 dollars by saturday or you cant get him back! Please anything helps we need Twinkie back hes part of a family and a community!! any donation helps we need him back!
