The Worst Humiliation and Treatment. Rude!!!!

I have never been so humiliated and disgusted like I was today. Literally ended up crying at a store because of a lady that gave me so much hell. I bought a printer at game stores in Westgate, ended up having to return the printer at the Game stores in Cradlestone because it is closer. Upon my arrival I was asked for the card I used to purchase initially and I gave it to the lady whom I forgot to take her name. A very nice lady for that matter. When she presented the card to Gugulethu Ngcobo who was at the customer service desk, Gugulethu immediately told her that the store doesn’t have money and she doesn’t understand why I didn’t go back to Westgate. I told her that Craflestone is a stone throw away from where I live and that’s why I went to Cradlestone instead of Westgate. She then immediately told me that she will return the money in my card in which I will receive in 7 days. I told her that I am unable to wait for 7 days. I asked is there not an alternative where I can leave the printer and then collect my money tomorrow in the afternoon, she said NO you will have to wait for our call and if we don’t call you that means we didn’t get the money. That then became an argument between myself and Gugulethu who then 1st accused me of taking a picture of her without her consent, then went off to accusing me of harassing her and threatened to call security to escort me out of the shop. She literally called a lady from security and told her to throw me out of the store. The security lady tried to apologise and defuse the situation and arrogant Gugulethu carried on with her bullying and lack of customer service. I demanded her to call her manager and regional manager and she blatantly still refused. She threatened me again by telling me she would give me R5 worth of 3.5k and later she says unfortunately we cannot give you that money. I have never been humiliated so much by a person that calls themself an Admin Manager and was the manager on duty at the time. I have hypertension and could’ve fallen in that shop because of the treatment and trauma I was put through. Game Cradlestone makes customers cry in their store because they literally bully customers and threaten them to throw them out when they speak out for themselves. What had our country come to? Does one not have the right to refund or return at a store of their choice? Does one need to go through so much trauma when approaching our retail stores?
