Ross Dress for Less

Yesterday my mom went shopping and Ross at manhattan blvd, harvey, La and she bought 4 items and the store cashier charged her for 5 items my mom went back to tell the lady what happened the lady went and called the manager but the employees beside her were laughing and making fun of her because she was hispanic and don't know that much english even thought my mom was trying her best to communicate, she found somebody to translate for her, the store manager went to check the cameras and checked my mom's bags without permission. My mom had such a bad experience that she is embarrassed about coming back to that store she came home crying, feeling humiliated. She is also thinking about suing the store.
