Family Dollar complaint: Hours of operation disrespectful employees

I shop at this particular store daily and ever since the new team has started working at this location it’s been problem after problem. Never open on time, when they finally do they’re playing vulgar music that’s definitely not appropriate for kids. When you ask her to turn it off she goes into a tirade of insults. I don’t know her name as she refuses to give it. However, she seems to be Jamaican, she has dreadlocks and a foul mouth. Again, I shop there daily and never had issues before.. Yesterday i was there in the pet aisle and i wanted to grab some dog treats, but she refused to move! I went around the aisle and she blocked me again! I asked to speak to a manager and she simply said that she IS the manager! This is something the needs to be addressed! As she stated write a complaint, so that’s what i am doing. Hopefully it doesn’t get ignored especially since she is so confident that a complaint won’t result in anything being done.
