My mother faces public humiliation because of Edgars staff negligence

Edgars causes my mother humiliation due to their staff negligence. My mum made a purchase from Edgars at the Ballito junction on the 3rd of August 2018 and she went to return the blouse on the 26th of August 2018 she had previously bought and thought she would take something else to her liking. Upon entering the EDGARS store the alarm was beeping at the entrance. The security lady asked to look at her packet and noticed that an alarm tag was still attached to one of the items of clothing in the packet. My mum was so shocked and appalled upon seeing this. The security lady then took the garment and removed the alarm tag and returned the packet back to my mum . My mum didnt take this lightly ,she had called to speak to the manager who she complained about how *********** her staff is and the humiliation she faced. This was utterly humiliating and embarrassing because other customers in their store thought my mum stole from the store. Howcome the alarm didn't ring before when my mum left the store when she made the previous purchase.?it goes to show the kind of security measures Edgars has in place in their stores. The manager even told my mum the security lady shouldn't have taken out the alarm and given you the packet. She apologised for the fault and said to my mum she will deal with the cashier who made this error. She had also said another guy in customer services will assist my mum in giving her some sort of compensation for the negligence of the store. Despite the humiliation my mum faced she still made further purchases from the store. Once she was done she had gone to customer services and asked to speak to the guy who said he will sort out this fault. When she got there she was told he had left the store and gave another lady to attend her. This is so ********* as he gave his word that he will assist her. When my mum was attended to by the lady at customer services she was just given a R100 gift voucher for the humiliation she faced. My mum is elderly, she just accepted it thinking it was fine. But it is infact NOT fine!!!, is this all that EDGARS can compensate for the humiliation my mum faced ??? She was treated with no respect. We purchase regularly at Edgars and we pay cash not CREDIT!!!! We are law abiding citizens and loyal customers of Edgars how can we trust shopping in a store that lacks ethics and principles. A store where staff run away from their duties and cause innocent people like my mum to be publicly humiliated. This is not acceptable, how is Edgars going to compensate for the negligent behaviour of their staff? Their security personnel should come into question? If my mum didn't have her previous docket with her I shudder to think of the consequences she could have faced with the law all because of the incompetency and negligence of Edgars staff. My mum could have been arrested yet she was an innocent victim in this entire ordeal. We seriously need to think about where we shop and how can a reputable store like EDGARS treat their customers in this appalling manner. I would really like to know how is Edgars going to fix or compensate for the humiliation my mother faced. Is a measly R100 voucher going to fix the public humiliation ??? This is just unacceptable.
