Feel a little bit frustrated disappointed

So on Facebook there's this mom's group and this woman was giving away a bunch of clothes I told her what time I would meet her and she set out everything with a sticker with my name on it and I picked it up together but later realized that on Facebook there was another woman interested in the same item so I wrote to her did she mean to put everything together and she said oh no it was a mistake I was going to gift one item to another woman and I got upset because why put it on the bench at the time you know I was going to pick up she even said the lady came over late at night and I was there the woman giving the clothes away was there and I'm frustrated because she knows I picked it up and she made the other woman waste gasoline to drive there instead of writing it has been picked up. I asked her yesterday so I could return it because she's far She wrote me today that yes it was for the other person but it's okay if I accidentally took it and basically she wanted me to feel bad for her mistake it's irresponsible now I have to decide to 1. Keep it. #2. Reach out to the other person and set up a meeting to give it to them. #3 return to original woman giving away the clothes.

It's a stress it's like originally she asked chose me first said do you want everything I said yes. Then another woman asked for the items and I told her at exactly what time I would be there and she said okay I will leave everything for you there and it's like if it was for someone else why not put a note or a sticker with there name or set it out when they arrive or somewhere else not the exact spot

So what would you do?
