What would you do?

So since I was like 10 weeks I saw the stroller that I loved, & I had my decision made that I wanted that one. I’m currently 25 weeks & some few weeks ago my sister in law asked me which stroller I wanted, that she was going to get it for me. I told her I kinda felt bad asking her for it & she said not to worry that she was gladly to. So I sent her which one I wanted, yesterday she sent me a picture of it & it’s not the want I had said. I was trying to be flexible about it & read upon the reviews, they were all negative :/

I told my boyfriend that I didn’t like it & he kinda got upset at me, idk if I’m in the wrong but I’ve had my mind set to the one I liked, we didn’t buy it on our own because she offered herself, at no point she said she was gonna chose it for me, otherwise I would’ve just bought it myself. How would you feel or what would you do if you were in my position?
