is my employer shady

I recently accepted a job at the mall working as a sales associate in a small women’s luxury clothing store. They don’t have a website. My employer said training would take 30 ish minutes and it isn’t paid. It ended up taking an hour. The girl that trained me let me know that I would be by myself for all my shifts so I decided to stay for the hour and really learn. I was surprised by this. My employer owns the business. I was added to the group chat on telegram before starting my first day of work as she sent me a link via text. Also, it’s only 5 employees (myself included) and they communicate via telegram instantly. It’s a family business. On my first day, I learned the really foreign customers that come in to negotiate the price are the ones that she (employer) caters too. If a customer wants a cheaper price or discount, it’s communicated via telegram and my employer would respond immediately to see what kind of discount they can get so as long as they make a sale. Clothing in the store ranges from 400 to 800. I assumed in good faith that my employer would have me fill out forms on my first day but nothing. I feel stupid. She asked me to send her my drivers license to be added to payroll 2 days before my first day. She has me scheduled to work tomorrow and next week. After I finished my morning to afternoon shift, another girl that I haven’t met came in to take over and do the closing shift. Before leaving, I asked her what is the payment process like and she said that my employer would have me fill out a w2 form and ask for my direct deposit. She then walked back to the break room and so I left. She seemed nice but cold. As soon as I finished my shift (today), I texted my employer that I would need to fill out the necessary forms to ensure that I am getting paid and it’s standard practice to fill it out before starting so I’d like to fill that out. It’s been hours and she hasn’t replied back. I haven’t been kicked out from the group chat but I do feel something is being planned. This is all so weird. There is no transparency. I feel she does not disclose the important info that is needed from an employer to an employee. I don’t think she plans on paying me nor do I just give out free labor. How should I go about it?? Also I apologize if it’s in the wrong subreddit!
