A girl at LB Nagar Cross roads

Hi me(26 M) approached by a girl (around 24 F) to let their parents know about her current location on phone. She handed me her phone who's on other end her mom/some relative asked me where she is and I told. She asked me to help the girl get to metro station by guide her an auto. I said ok and told the girl. She's on phone with her relative and talking something. I waited few minutes. I suggested let me book an auto to metro from here so you can go as she didn't have uber on her phone. She didn't say anything and moved to side like I'm annoying her. She kept on talking on her phone without telling me anything. I just boarded my bus and left without saying anything to her. I overheard her telling on phone, "He's boarded the bus and leaving as I'm talking on phone with you" . Did I do it right?

My concerns: I couldn't approach to ask her one more time her as she's stranger and a lady. Looks like she's not interested in answering me, why should I spend mine (time) to help her?

If I did asked her and she moves away, it would seem like I'm annoying her.

TLDR: Left without saying anything to a random girl who asked for finding a way to metro station.

Edit 1: Adding contextual information

I believe it is not a trap. Why because I'm going to book the auto on my phone, and only she's going to enter it. How could she know which auto Ola/Uber going to assign for me? Looks like she's got trust issues. That's all I can say for sure.
