Terrible treatment at MTN Promenade store

I'm extremely unhappy about the treatment I've received from one of the consultants at the MTN Promenade store this morning. The consultant was very rude. I needed to have a sim swap done. She didn't check whether my number was contract or not beforehand and then said that I would need to buy one outside. With attitude. I did this and returned. She then said I must open my phone and put the sim card in. I said I do not have the ejection pin to open the phone and asked whether she had one. She said no and I quote, "we don't have those things lying around". I then went on to ask the other people in store. The MTN host said that I could use an earring and he gladly helped me, but it did not work. I said I would be back and walked out the store, looking for people to assist me. I got help from one of the workers a few meters away from the store. I went back and then she finally assisted me. She then realised that my number is on contract number and only then offered me a simcard. And this is after going through the trouble of trying to buying another sim card and having it rica'd. I needed to pay and gave my bank card, but then it declined. I then gave her the cash. I really feel that the treatment I received was uncalled for. And had I been asked the right questions on the onset, I would not have gone through all this unnecessary trouble. I'm not going back again and once my contract is finished, I will port to a different service provider who understands what customer service is. Please train your staff on how to treat customers.
