Burger King review: manager/ rude ness

I had dropped my daughter off for work to get a text from her that she was yelled at by the manager in front of customers and this has happened multiple times to my daughter. And the manager satisfy do not call the upper of the store that she needs to talk to her but every time she feels like she is not being treated the way she is supposed to. She has yelled numerous times at my daughter in front of customers or even if it's in the back you can still hear her when you go to get your order. Every time I try to contact the customer service or make a complaint nothing is being dealt with with that manager. My daughter feels unsafe every time the manager is there and I will not tolerate my daughter being yelled at that is not how you treat a co-worker and I've seen her deal with coworkers that not my daughter and came out crying because she's talking to them rudely.
