Should i have been treated like that?

I was dress shopping with my friend today, I was in the change room trying on dresses and one dress was on the floor by accident. A lady knocked on the door very loud (That's okay.. like a lot of people do that) and she was like VERY overly rude (like you can ask nicely) she said "Excuse me? can you please pick up the dress that is one the ground at hang it up rather than just leave it on the ground?" And i was like oh my mistake.. I hung it up. I walked out of the change room to look at myself in the mirror with my dress with my friend and she was just STARRING. I went back in and the same thing happened i left a dress on the floor by accident and she knocked SO lound and asked me to pick it up and like ya i would have noticed it on the ground and picked it up in like a min she doesnt have to keep being a ****** and I got so fed up I just put it on the ground and I went out to show my friend a shirt and my friend told me that "The employee was sitting outside my change room watching every move I make" and i was so pissed and then I went back in and then the dresses were still on the ground and she said can you please pick them up like she wont leave me alone and I was busy trying to get a zipper up so she can wait ONE fricken second and I told her that and she was like "Well you have to pay for dresses you wreck" like I am going to fricken wreck a dress if it touches the ground and I said "Yup I will once i get the zipper up on a dress and she kept biatching at me and said I can leave the store and I walked out at told me not to be so rude just cause i told her to stop watching me under the change room and OMG she told me to leave the store and she was a FAAATT ****** and omg i cant believe she treated me like that everyone was starring and how do i get ahold of someone to report her and get her in trouble?
