My cousin is 11 and I'm just a little bit older. How do I get her to stop stealing my stuff?

Okay, so a couple days ago, my little sister told me that my cousin had stolen my portable charger from me. I wasn't that surprised because she'd stolen a lot from me before. So, since my little sister was going to my aunts place today, I told her to text me when she found my charger, and my washi tape, and whatever else she stole. This was so my cousin didn't know that we were onto her, because if she did, then she would hide everything and it'd be harder to get back. Now, my cousin's texted me saying that she was the one texting me from my sisters iPad. She said, "I texted you from _____'s iPad. Haha." Now, I want to get my stuff back, but I don't know how to tell her to give it back to me. I want to text my aunt and let her know, but I also want to tell my cousin to give everything back to us if she doesn't want to get in trouble. I can't really do anything until I talk to my sister, but I'm not sure if she'll be the one to answer. What should I do?
Added (1). Also, should I text my cousin and say "I know you took my stuff."? Because she'll just text me back saying "I didn't. You're lying. I bought that, it's mine." I want to get everything back because that portable charger was expensive and she had no right to take it. I want to text my aunt while she's at work, but I need to talk to my little sister who's at my aunt's house with my grandma first. I already tried texting her, but she won't reply.

Is it odd if I go to the same coffee shop for years but don't know their WIFI password and ask for it? What will the workers think if I ask?

I don't use the Internet much when I'm there but I usually just use my LTE on my phone or use my phone as a personal hotspot if I need Internet of my iPad pro. It feels strange having never asked what the coffee shop's WIFI password is.
