The Worst Customer Service at Pick n Pay

So I went to the kiosk at Pick n Pay Tembisa Megamart to buy some spice and electricity. When I get to the front after waiting in the line while he and his supervisor Sharon,I assume, I approach the cashier(who didn't have a name tag) and he scans the item and I then asked to purchase electricity. He the says that they don't allow purchases without the presentation of a card that has the meter number as proof. I questioned why that is the case only to be pompously told " It is the rules" in vernac. I then questioned if this is the general rule across all Pick n Pays because when I go to a Pick n pay in Centurion, Lyttleton and Irene or any other Pick n Pay for that matter I am not asked for any proof because I have memorised it and the system does confirm the initials and surnames of the municipal account holders(my parents). Mind you , it is not the first time I am buying electricity from this exact same store. Every time I go there, I always end up asking for a supervisor who eventually tells the staff member to proceed with the purchase as it will confirm. Today ,for some odd reason , even the supervisor refused to help me and then had the audacity to tell me to go the manager and he will also tell me the same thing. WHAT!!!! I must go to the manager? To cut a long story short, I started to take a video of this whole ordeal and they said I am not allowd to take a video. I eventually told the staff member and his supervisor Sharon that I am going to post this on social media. Hello Peter is just the beginning. I ended up being pulled from the counter by the security guard and escorted to the Manager who's name is Jeff Mabuza and the first thing he said to me was "What's your problem?" without even acknowledging me. He even said to me that I must go complain and that he will deal with me tomorrow. I didn't get my electricity and had to go buy at Shoprite which was quite a distance and they even refused for me to pay for the spice. Basically I am sad that customer service in the affluent areas is so much different from the customer service in the location. It is such a pity that`they treat their customers this way only because they have this notion that we are all illiterate and don't complain .
