Rude customer service staff At Makro Ottery

I recently returned back to SA with my Russian wife and 1 year old baby who are here in South Africa for the first time, a friend recommended that I buy a children's book at Makro that is good for 1 year old babies. So we decided to go to Makro in Ottery where I was greeted with disrespect, threats and humiliation in front of my wife, child and a entire store by the ladies at the Customer service desk. So at Makro if you want to buy anything you need to have a Makro card which I did not know so I went to the ladies at customer service to get one, they gave me a form and told me fill it out, after I did that I gave it back to the lady and I could hear they were talking about me while they were looking at the form I filled out, I did not pay attention to the gossip and waited for the card, soon after the lady asks me what is your surname and politely reply it's on the form which she reply back and says yes I can see but I'm asking you what it is, so I tell her what my surname is and she types away while looking and gossiping on about me like I am not there, after that she gives me a card and I see that they got my surname wrong, I then tell her this is wrong and she reply to me this is normally how you spell this surname and I did ask you to spell it, so I told her you did not ask me to spell it but I will gladly spell it for you at this point the lady next to her tells me do you know who you talking to, she is older than you and you disrespecting her. At this point I am getting worked up because not only are you gossiping about me you now also accusing me of something that I am not doing. So myself and the lady that is telling me I am disrespectful gets into a argument and she decides to tell me that I must not speak to her like that I must go speak to my Child and Mom like that at this point I'm ****ed off because now you talking about my Mom and my Child and I raised my voice a bit in this argument and she threatens me with security that will kick me out of this shop and I rep**** to her and said get the security, at this point the manager on duty stepped in and told her to relax and stop going on but she just ignored this gentleman and continued to argue with me, the manager then pulled me aside and apologized and ask me to explain what happened and as I explained what happened this lady is still going on and not even listening to her manager who told her more than once to back off. This is all for 1 book that I went to go buy for my child. my wife was shocked and scared as she is not use to this kind of behavior from staff. I just want to say thank you to Markro Ottery customer service for a hardy welcome back into the country I will most definitely not be shopping or recommend anyone to shop at the Ottery Makro.
