She probably thought she could get away with it. And if you didn't have proof of delivery, she probably could have. Best of luck OP!
Contacted eBay. They told me to contact the buyer and see what her reply was. If she didn't reply or still insisted she didn't receive it, I could report it as stolen and they would get involved. They asked me for her ID and item number. I told them I would give it to them if she didn't cooperate.
SO, GUESS WHAT? I just emailed her and she got right back to me. I told her I had proof of delivery. She said her sister got it and she just found out and didn't know how to tell me. Well, I guess selling it was a way to tell me, right? I do not care, she said she would return it to me. I just paid her to ship it back. I will await it's return and also watch to see if she pulls her eBay listing. Hopefully, she is telling me the truth!
I will keep you updated.
Thanks for all of your help!
Thank you all for your kind words. I do believe she is telling me the truth. Her feedback is impeccable and I do not wish to reveal her ID. If she doesn't follow through on her promise and send it back to me, I of course then will have a different feeling about her. I try to see the best in people. She immediately got back to me and just ended her listing.
So, she didn't stop and think.."hmmm where did this bag come from since I didn't buy it?" and instead said, "well, now that I have this bag I never bought, I will clean it and sell it..even though someone contacted me in the past looking for a bag she mistakenly sent me?" You must have some tolerence level because I wouldn't be able to see any good in a person like this.
Glad to hear you resolved it in your favor, though!
