Rude manager and employee

I have been ridiculed and laughed at by the manager and staff member me and my sister have been ridiculed more than once by these 2 staff members on numerous accounts .The first incident was when I was returning a dress because of incorrect size the manager stated that " What should she do that I want to return the dress " and proceeded to ask my sister who was with me what she was looking at this is very unprofessional and unpleasant on another incident she asked one of her male employees to follow me around the store and the manager once took pictures of me on her phone and called me by name how she knows my name nobody knows recently my sister took a picture of the empoyee because the employees do not wear name badges how should we make an complaint when we don't know employee names.thats when the employee in question called who I think is the manager saying "Rosie friend they are here " and they are taking video that's when the manager stared down my sister and got aggressive and asked what is the problem my sister tried explaining by the time she got to finish her complaint the Manger still proceeded to badger her with the question what is her problem the manager bolted out the door to get security of hemingways mall to escourt us claiming I came in rude and insulting to them to the security guard.I have complained to management of hemingways mall I got an email calming we are the problem and we insulted the staff of the fix and the management of hemingways say they are concerned of my behavior but I'm the person making the complaint.i don't think I will be visiting the fix hemingways mall anytime soon I have been treated like a common ******** for exercising my right and revictimising me with the email I have not received a single heartfelt apology from The manager or the staff member or the security guard who embarrassed me publicly .
