impairment of Dignity suffered at hands of Edgars Staff

On the 26th December 2017 while in Herm****, I visited the nearest mall to pay my retail store accounts. At the Edgars store there were two couloured staff persons attending to items on their disheveled counter, I enquired from them where one should pay but was crudely rebuffed, an African lady and staff member kindly gestured me in the right direction. I handed my account card to the couloured cashier who never asked what I wanted but instead just scanned my card. Whilst she left the counter in a disheveled state, and after scanning my card she furtively and arrogantly in the midst of other clientele stated that my card was **********. In amazement and taken aback I interjected “excuse me”? She loudly repeated once again in an arrogant and demeaning manner “you can’t buy anything on this card it’s **********”. I was shocked, embarrassed and irritated at the insolent and disrespectful behavior notwithstanding the impairment to my dignity and rep**** “ I want to pay my account you imbecile”. She then retorted that she assumed I was purchasing items on the still disheveled counter. She then however forcibly shoved the card into my hands and said that’s it you leaving my store get out!! I told her that the store was not hers that she was an employee. She proceeded to walk around the counter and started to usher me physically out of the store in a discourteous manner. Whilst doing so she called me a “***** ***” and told me to “**** off” in front of the Edgar’s clientele. I have been an Edgar’s account holder for over 20 years, and have never experienced such emboldened behavior from any worker at Edgar’s or for that matter in any retail store ever. I was dumbfounded by the rather callous and cavalier attitude with which this coloured cashier proceeded to deal with the clients of Edgar’s without any fear of reprisal. The emboldened attitude was needless to say disconcerting. I am seriously considering my options on how to deal with this matter going forward given that the employee was acting in the scope of her employment.
