Despicable and Unbearable Customer Service

I am highly disappointed, I have been a Rage Customer from 2017 and the customer service I have received today at Rage Eyethu Mall was so unpleasant and embarrassing. Today I went there to re-activate my account so that i can get Christmas clothes for my 2 daughters, as a single parent I still use the green book ID and because it is an old ID it is not in a good condition as it should be and because I have been unemployed I have not been unable to pay for the smart card as yet but have app**** for it since now I have managed to secure a job recently. I got to the cashier, and she asked for my ID which I had explained to her before providing it that it is a green book when I took it out, she started laughing and literary displayed the ID to the other customers that were in the queue and telling them to look at the ID at that point I was thinking POPI ACT but I decided to ignore her with hopes that she would stop since the whole situation was embarrassing and very unprofessional, she went ahead to tell me they are unable to reactivate my account that was stopped because I had lost my card, when she said they are unable to help I asked her is there anything else I can do because I really need the clothes for my kids she then said " Chomy you are desperate ne" bear in mind she is saying this out loud with other customers laughing with her of my situation I rep**** by saying I need clothes for my kids she then said why in December I should have sorted the ID first before going to the store all this is a joke because it's said out loud Infront of other customers she passed me back my ID and told me I am in trouble the kids need the clothes, i hate everything about the experience I had today. I am so disappointed at Rage as a company and Enterprise since i have been an existing customer for 8 consecutive years. if you don't have the smart card or in need of help, the disrespect I received today was hectic.
