Possible sex trafficking??

I was with my sisters at the Walmart on 290 at around 8:30-8:45pm today (6/23/22). Three of us were looking at kitchen organizers on a very empty aisle, then we were approached by a middle age lady with very messy red lipstick, behind her a young girl around 14 playing with her hands. She asked us if we spoke English (we’re Asian) and then invited us to Bible study. I don’t remember exactly what she said but despite us saying “no thank you” and that we’re Buddhist multiple times, she insisted until I kept waving my hands. She said well if we change her mind then we can come find her (but did not give us any contact information). After she back away from the aisle (yes not go through, backed away) my sister informed me that she’s seen multiple videos regarding sex traffickers trying to get girls with the same tactic, usually a woman and sometimes a child with them to seem more trustworthy. Then I remember the young girl behind her. The lady is Hispanic and the girl is black and she seemed uncomfortable and shy. She looked down and played with her hands the whole time. Then I realized how weird it was for her to approach three young girls alone (26, 19, 7) in an empty aisle at WALMART to invite us to bible study (or maybe it’s just weird to me because idk how these recruiters usually do things) but I felt incredibly uneasy after thinking about everything. Also the many amber alerts I’ve been getting lately about missing children made my head spin and I felt so sick. So then, still at Walmart, I dialed the non emergency number to report this hoping that it can leave a trail somehow and even if it’s nothing at least I called. The whole time I looked around seeing if I can spot her again but I couldn’t. I am currently still on hold. It hung up on me once so I had to redial. Any input would be greatly appreciated! Keep yourself and your children safe out there!
