Horse showed up on my account?

So I've been on a long break from the game and am trying to get back into playing. I went to the rescue center to look at the horses there, specifically the TWHs. I clicked into the profile of a filly that was listed. I looked over her page a bit, then clicked the home button on the navigation bar. When I went to look at my list of horses from there, I noticed I had one that wasn't in a specific division, which was weird as I have not bought or adopted any horses in months and all my previous horses are in named divisions that are all locked. Looked at the horse and its the filly I had looked at that was in the RC. I checked my banking history and even that shows I adopted her. I have no idea where the adopt button even is on the horses page as I wasn't paying attention to it as I had no intention of adopting or buying any horses until my current herds have sold. I know for a fact I never clicked the adopt button on her page. Why is it saying I adopted her? Is there any way to get my money back and return her to the adoption center? Thanks in advance to any who answer! I know this is a strange thing to be asking about, but I can promise you that I did NOT adopt her of my own accord.

Do you have your transfers on? A random member may have just sent you their horse they didn’t want, but I’d assume you’d get a notification for something like that.

I do, but it doesn't say it was transferred. My bank history says I actually adopted her and it took the $200 adoption fee out. I was looking in the adoption center again last night and found where the adoption button was, but I know for a fact I didn't click anything anywhere near it.
